Summary: Re: Sendmail.cf for an HP 715 into a Sparc 10/41

I received several solutions to this problem and I appreciate each and
every one. I ended up using the first one I read this morning from
Jonathan B. Horen of Applicon and the problem was resolved. (Thanks Jonathan!)

Once I had the sendmail.cf, it was a simple matter of changing the sections as
necessary to match our installation and using sam, restarting the sendmail
daemon. I did run into a small snag, on the SPARC 10/41 system the sendmail.cf
file is located in /etc and on the HP 715, it is located in /usr/lib. This was
the only problem and after the new sendmail.cf was put in place, we were in
business!!!

Thanks again for all your help, this is a great way to get things done!

This message contains all the suggestions including the sendmail.cf files
in case anyone else should run into this issue.

Attached is a copy of the sendmail.cf we use (major Sun network,
with 2 HP-715/33 workstations) -- hope it helps.

NOTE: it is configured for site-hiding (the DY macro) on outward-bound
      mail (so that recipients receive mail from user@domainname), and
      for host-hiding (S10/S20) on internal mail (so that recipients
      receive mail from user, w/o host or domainname).

############################################################ ############################################################ ##### ##### ##### CAVEAT EMPTOR ##### ##### ##### ##### This configuration file is suitable for use on ##### ##### most HP-UX systems and can be installed, ##### ##### unmodified, as sendmail's configuration file, ##### ##### /usr/lib/sendmail.cf ##### ##### ##### ##### Modifications that reflect this host's mail ##### ##### environment may be needed.

################################################################################ # Localizations: # ################################################################################ # # # While this configuration file can be used unmodified, it may be # # appropriate to make some or all of the following changes to this # # configuration file to incorporate local information or preferences. # # # # Detailed descriptions of sendmail.cf syntax and complete list of # # the configuration options can be found in the documentation. # # # # Use the Nameserver (option I): # # # # If this host is using the domain nameserver, the I option should # # be set. In most cases, sendmail will be able to detect whether # # the nameserver is in use and will automatically do the right # # thing. However, in some cases it will incorrectly appear to # # sendmail as though the nameserver is not being used, for example # # if the nameserver has not finished loading its data and is not yet # # responding to queries. If this host normally uses the nameserver, # # messages should be deferred when the nameserver is not running. # # # # If the I option is set, if an MX record lookup or gethostbyname() # # call fails because the nameserver is not running, sendmail will # # defer the message. # # # # If the I option is not set, if an MX record lookup fails, sendmail # # will assume that the nameserver is not being used, and that there # # are no MX records, and try to connect directly to the host. If a # # host name lookup fails, sendmail will assume that there is no # # entry for the host and return an error. # # # # By default, the I option is not set. To set it, uncomment the # # line: # # # # # OI # # # # Site Hiding (macro Y): # # # # It may be desirable to "hide" the name of a host generating SMTP # # mail, so that replies need not be directed to the particular host # # on which the message originated. This simplifies moving a user's # # mail home from one host to another, and gives the appearance of # # mail being generated by a unified organization rather than a # # collection of hosts. # # # # By default the sender of a message routed via SMTP is identified # # with the header line: # # # # From: Full Name <user@host> # # # # where "host" is the canonical name of the local host (macro w). # # # # If the macro Y is defined, the value of macro Y will be appended # # instead of the local host name. The macro Y would typically be # # defined either as the name of a local mail hub, or as the local # # domain name. Although the name need not be the name of an actual # # host, this scheme requires that some host recognize the name and # # be able to route mail to the originating user. # # # # For example, to identify SMTP mail from the local host as # # originating from the domain poo.bah.edu, Y should be defined by # # replacing the line: # # # # # DY # # # # with: # # # # DYpoo.bah.edu # # # # An outgoing SMTP message from user "fred" at the host "burb" # # would have the From: header line: # # # # From: Fred User <fred@poo.bah.edu> # # # # Assume that the host "porpoise.poo.bah.edu" is to accept and # # forward mail for the domain poo.bah.edu. In order for users at # # other hosts to reply to such messages, there are two things that # # must be done: # # # # 1) Replying hosts must be able to map the name poo.bah.edu to an # # internet address or MX record. # # # # 2) Some host must be prepared to recognize mail addressed to # # "user@poo.bah.edu" as local, and be able to route such mail # # appropriately. # # # # To satisfy 1), the nameserver for the domain bah.edu must have # # either an MX record for the name "poo" directing its mail to the # # host porpoise.poo.bah.edu, or an address record mapping the name # # "poo" to an internet address belonging to porpoise.poo.bah.edu. # # Do not make "poo.bah.edu" a CNAME for porpoise.poo.bah.edu, # # because in that case a recipient may canonicalize the sender # # address "user@poo.bah.edu" to "user@porpoise.poo.bah.edu", which # # defeats the purpose of site hiding. For the same reason, if a # # replying host uses /etc/hosts or NIS (formerly known as Yellow # # Pages) to do host name to address mapping, the entry for # # poo.bah.edu should be a separate line, not a host name alias. # # # # To satisfy 2), on porpoise, the name "poo.bah.edu" must be added # # to class w (see below), and there must be mail aliases for all # # users on systems with macro Y defined as above. For example: # # # # fred: fred@burb.poo.bah.edu # # # # Aliases for Local Host (class w): # # # # This configuration will automatically recognize that mail to users # # at the local host or any of its host name aliases or CNAMEs should # # be delivered locally. Other host names that you wish to recognize # # as local can be added to class w as either a simple class # # definition (Cw) or a file class (Fw). Any names added to class w # # must be canonical names. # # # # For example, by default, only the server cnode of an HP-UX cluster # # runs the sendmail daemon, and mail from the clients is sent out # # with headers indicating that it originated on the server. # # # # However, you might want the server also to accept mail addressed # # to users at the clients. You could have nameserver MX records # # directing mail for the clients to the server, and make the server # # recognize the clients' host names as local. If the clients' names # # are ick, ack, and ock in the domain urk.com, the class w could be # # augmented as follows: # # # # Cw ick.urk.com ack.urk.com ock.urk.com # # # # Message-ID Header Field # # # # Associating a unique Message-ID header line with every message can # # be useful for tracing messages through the mail system. This is # # not the default because it makes the syslog file grow 50% faster. # # If the configuration file line: # # # # # H?M?Message-Id: <$t.$i@$w> # # # # is uncommented, sendmail will generate a Message-ID header line # # for each message it routes that does not already have one. The id # # contains the date (GMT), in the form YYMMDDhhmm, the queue ID # # associated with the message on the local host, and the local host # # name. # # # # In any case, if an incoming message already has a Message-ID # # header line, sendmail will preserve this line. # # # # Postmaster Copy (option P): # # # # If this option is set to a valid address, when an undeliverable # # message is mailed back, a copy of the message header (but not the # # message body) is delivered to the PostMasterCopy address. It is # # suggested that this address be "Postmaster" since RFC 822 requires # # that there be a valid Postmaster address on all mail systems, and # # since sendmail also attempts to deliver undeliverable error return # # messages to Postmaster. # # # # Postmaster should be aliased locally to the (local or remote) # # address of the person responsible for mail system administration. # # # # To enable this feature, uncomment the line: # # # # # OPPostmaster # # # # If desired, replace "Postmaster" with the appropriate address. # # # # Dumb UUCP Hosts (class G): # # # # If your host has UUCP connections to hosts running "dumb", # # i.e. non-RFC 822 compatible, UUCP mailers, you should define the # # class G as a list of these hosts. This will cause UUCP mail to # # these hosts to be sent via the dumbuucp mailer rather than the # # normal uucp mailer. Since "dumb" mailers will not add their host # # names to the return path in the From: header field, the dumbuucp # # delivery agent deletes From: header fields from mail for such # # hosts. In most cases the mail system on the host where final # # delivery is done will be able to generate a correct return path # # from other information in the message header. # # # # For example, if your host has UUCP connections to dumb UUCP # # mailers on hosts rrgh and feh, the class G should be defined, # # on the line beginning with CG, as follows: # # # # CGrrgh feh # # # # Trusted Users (T): # # # # If other hosts login to your host to perform UUCP mail transfers, # # the login ids used by these systems must be defined as trusted # # users. The login id "uucp" is already defined as a trusted user. # # If necessary, add lines of the form: # # # # Tusername # # # # to the Trusted Users section of this file (lines beginning with T). # # # # Logging Level (option L): # # # # Logging level determines the classes of events which will be # # logged by sendmail in /usr/spool/mqueue/syslog. By default the # # log level is 10, which reports successful deliveries (and the # # mailer and host used for delivery), queue daemon startup, alias # # database rebuilds, and various errors. More detailed information # # is reported with higher log levels. In particular, log level 11 # # reports the MX host (if any) and internet address to which mail # # was delivered. Refer to the documentation for details. # # # # Note that log level also affects the information reported by # # sendmail -bv. At log level 10 and higher, sendmail also reports # # the mailer and host that would be used for addresses that are # # "deliverable." # # # # The option L is defined on the line beginning with OL. # # # # Delivery Mode (option d): # # # # The default delivery mode is "background": the user agent # # invoking sendmail will return immediately, and sendmail will route # # the mail in the background. Other options are "interactive": # # sendmail will not return control to the program invoking it until # # the mail has been routed; and "queue": sendmail will put the # # message in the mail queue and a sendmail queue process will route # # the message later. Delivery mode is defined on the line beginning # # with Od. # # # # Error Reporting Mode (option e): # # # # The default error reporting mode is "p": if sendmail detects an # # error before it finishes sending a message, error messages are # # output to stdout; if errors occur later they are mailed back. # # Other options are: "w": if the sender is logged in, any error # # messages are written to the sender's terminal, otherwise they are # # mailed back; "m": error messages are always mailed; and "q": no # # error messages. Error reporting mode is defined on the line # # beginning with Oe. # # # # Read Timeout (option r): # # # # If the program transmitting a message to sendmail hangs, or if an # # SMTP peer goes down, sendmail's read will time out after this # # interval. RFC 1123 section 5.3.2 discusses appropriate values for # # this timeout. Refer to the sendmail documentation for the syntax # # for specifying time intervals. The read timeout is defined on the # # line beginning with Or. # # # # Queue Timeout (option T): # # # # Messages in the mail queue which sendmail has been unable to # # deliver for this amount of time will be returned to the sender as # # undeliverable. Refer to the documentation for the syntax for # # specifying time intervals. Queue timeout is defined on the line # # beginning OT. # # # # Queue-Only Load Average (option x): # # # # In order to limit load on a very busy system, sendmail can be # # configured to queue up low priority messages rather than attempt # # delivery immediately if the five-minute load average is greater # # than some integer value, by default 8. This value is defined on # # the line beginning Ox. # # # # Refuse-Connections Load Average (option X): # # # # In order to limit load on a very busy system, the sendmail daemon # # can be configured not to accept SMTP connections if the five- # # minute load average is greater than some integer value, by # # default 12. This value is defined on the line beginning Ox. # # # ################################################################################

################################################################################ # Routing Options: # ################################################################################ # # # The supported routing options are described below. Options for # # routing SMTP mail, UUCP mail, X.400 mail, and OpenMail mail are # # described. # # # # To implement any of these options, edit a copy of this file # # according to the instructions for that option. With minor # # exceptions, noted where appropriate, the options are independent # # of each other; you can implement any of them or none of them. # # # # Some of these options require that you have installed and # # configured other software not part of the ARPA/9000 product. # # # # # # Operator precedence: # # # # It is generally agreed that mixed addresses, being ambiguous, are # # abhorrent. This configuration file interprets address operators # # in the order '@', '!', '%'. # # # # Changes to this precedence are not supported! # # # # Mixed addresses are resolved as follows: # # # # Address Mailer Host User Destination # # ------- ------ ---- ---- ----------- # # user%hostA@hostB tcp hostB user%hostA@hostB user@hostA # # hostA!user@hostB tcp hostB hostA!user@hostB hostA!user # # hostA!user%hostB uucp hostA user@hostB user@hostB # # # ################################################################################ # SMTP Mail Routing: # ################################################################################ # # # By default, all mail to addresses of the form "user@host" will be # # routed to "host" using the SMTP protocol over TCP/IP. If the # # nameserver is in use, an MX record may direct sendmail to route # # mail for that host to some other host acting as a "mail exchanger" # # for the host in the recipient address. If there is no MX record # # for the host name, gethostbyname(3n) must be able to return an # # internet address for the host or else the delivery will fail. # # # # You can arrange to mail directly only to certain hosts. Mail to # # other hosts can either be rejected as an error, or be passed to a # # "relay" host for delivery. # # # # Direct SMTP connection within local domain only: # # # # This option makes sense only if your site uses internet domain # # style host names. You can define macro L as the name of the # # "local domain" and mail directly only to hosts whose canonical # # names end with that name. For example, if your local domain is # # "envy.sins.com", you might define macro L as "envy.sins.com" and # # define an SMTP relay, in which case sendmail would send directly # # to "user@porch.envy.sins.com" but relay "user@foyer.pride.sins.com". # # Alternatively, if your host is on a closed subnet, you might # # define macro L as "sins.com" and only relay mail (through a host # # with an interface on an open subnet as well as on your closed # # subnet) to domains outside sins.com . # # # # To route only to the local domain, first define macro L. For # # example, to route directly to hosts in the domain sins.com, define # # macro L, on the line beginning DL, as follows: # # # # DLsins.com # # # # Then uncomment the line in ruleset 0 following the comment: # # # # # connect to hosts in local domain # # # # Finally, comment out the line in ruleset 0 following the comment: # # # # # try to connect to any host for user@domain # # # # Direct SMTP connection to hosts in class S only: # # # # You can define a file class S of hosts to connect to directly. # # This option does not make much sense if your host runs the # # nameserver or NIS (formerly called Yellow Pages), since it # # requires that you keep a static table up to date. An internal # # hash table is generated from the file when the configuration file # # is frozen or, if no frozen configuration file is in use, when # # sendmail starts up. Therefore, if the file from which the class # # is generated changes, the configuration file should be re-frozen # # and the sendmail daemon killed and restarted. # # # # The file from which this class is defined (by default # # /etc/hosts.smtp) should contain only host names to which your host # # can connect via TCP, as the first word on each line. It would be # # appropriate for the file to include host name aliases as well as # # official host names, and to exclude hosts that do not run an SMTP # # server. # # # # The file can contain internet domain style names. The current # # HP-UX version of sendmail can match multi-token names to class # # members. # # # # To define file class S, first uncomment the line defining class S # # from /etc/hosts.smtp, following the comment: # # # # # class S defines hosts to which you connect directly for SMTP mail # # # # Then uncomment the line in ruleset 0 following the comment: # # # # # connect to hosts in class S # # # # Finally, comment out the line in ruleset 0 following the comment: # # # # # try to connect to any host for user@domain # # # # Direct SMTP connection to nobody: # # # # This option makes sense only if an SMTP relay is also defined. A # # host (for example a single user workstation) may wish to send all # # SMTP mail through a relay. To arrange this, comment out the line # # in ruleset 0 following the comment: # # # # # try to connect to any host for user@domain # # # # Note that this option is not compatible with options 1 or 2 above. # # # # SMTP relay: # # # # If you are limiting direct SMTP connections as described above, # # by default mail to hosts outside the limits will be returned with # # an error. If you can connect to another host with wider network # # connectivity than your host has, you can use that host as an SMTP # # relay. Courtesy suggests that you get permission from the # # administrator of that host before relaying mail through it. # # # # Any host name defined as a relay to be reached via SMTP must be an # # official host name; in a domain naming environment this must be a # # fully qualified domain name. The canonicalization operator $[ $] # # is not applied to relay names. # # # # To set up an SMTP relay, define the macro S, on the line beginning # # DS, as the host name (not path) of the relay host. For example, # # if you wish to relay through the host blab.bub.edu, define S as # # follows: # # # # DSblab.bub.edu # # # # Then uncomment the line in Ruleset 0 following the comment: # # # # # pass unresolved SMTP addresses to the SMTP relay # # (don't relay source routes) # # # # Note that if you are not limiting direct SMTP connections in some # # way, SMTP mail cannot be relayed. # # # ################################################################################ # UUCP Mail Routing: # ################################################################################ # # # By default, mail to addresses of the form "host!user" is routed to # # the uucp (or dumbuucp) mailer only if "host" is in the class U, # # generated from the output of uuname(1). Addresses of this form # # referring to other host names are treated as errors. # # # # The following UUCP routing options are supported: # # # # pathalias external nameserver for UUCP: # # # # You can maintain a pathalias database to provide sendmail with # # information on how to route UUCP mail to hosts to which your host # # does not have a direct UUCP connection. This routing information # # is generated by pathalias(1m). Mkuupath(1m) creates a hashed # # database from the routing information, and uupath(1m) is used to # # access the database. # # # # To make sendmail use uupath, first set up the database as # # described above. Then uncomment the three lines in Ruleset 0 # # following the comment: # # # # # try to get a path to an unresolved UUCP address # # from pathalias nameserver # # # # UUCP relay (via UUCP): # # # # If your host has a UUCP path to another host with wider UUCP # # connectivity than your host has, it may be appropriate to route # # UUCP mail to hosts to which your host cannot connect through # # this other host, which will attempt to relay messages to their # # final destination. Courtesy suggests that you get permission from # # the administrator of that host before relaying mail through it. # # # # To implement UUCP relaying via UUCP, first define the macro U, on # # the line beginning DU, as either the relay host name or the path # # to the relay host. # # # # For example, if you wish to relay through the host pzzz, via the # # path rrgh!frr!feh!pzzz , define U: # # # # DUrrgh!frr!feh!pzzz # # # # If you have a direct UUCP connection to pzzz, define U: # # # # DUpzzz # # # # After defining the UUCP relay, uncomment the three lines in # # Ruleset 0 following the comment: # # # # # pass unresolved UUCP addresses to the UUCP relay (via UUCP) # # # # UUCP relay (via SMTP): # # # # If you can mail via SMTP to the host you wish to use as a UUCP # # relay, define the macro W, on the line beginning DW, as the name # # of the UUCP relay host. # # # # Note that in this case, the macro W must be a single host name, # # not a path. Note also that the name of any host defined as a # # relay to be reached via SMTP must be an official host name; in a # # domain naming environment this must be a fully qualified domain # # name. The canonicalization operator $[ $] is not applied to relay # # names. # # # # For example, if domain names are not in use at your site, and # # if the relay host's official name is pzzz, define W: # # # # DWpzzz # # # # Then uncomment the line in Ruleset 0 following the comment: # # # # # pass unresolved UUCP addresses to the UUCP relay (via SMTP) # # # # Note that there is some risk of generating ambiguous (mixed) # # addresses in message headers using this type of relaying, if you # # are passing mail to hosts whose mail configuration is not under # # your control.

This would require no change to the local # # host's sendmail configuration. # # # # So that users need not know which remote host is the OpenMail # # gateway, sendmail can be configured to route mail to OpenMail # # addresses via a designated OpenMail gateway automatically.

Does the HP have a local spool directory, or does it mount /var/spool/mail from the Sun ?

The first situation can be handled with a sendmail.cf like this:

### ### SENDMAIL CONFIGURATION FILE ### ### This is the sendmail.cf for a client who can make a TCP connection ### to a mail server. No local mail happens here, everything is sent to ### the server. Should work for just about any version of sendmail, ### i.e. doesn't use any e.g. Sun-specific features. Of coure, all ### userids on the client must also be known on the server, either as ### real userids or as aliases. Only the first section below should ### need any changes for a particular installation. ### ### Note that as opposed to the broken OR option in the sendmail.cf ### that Sun delivers, this configuration WILL queue mail on the client ### if it can't connect to the server. This means that the queue must ### be checked periodically, either by running sendmail in the normal ### daemon mode (e.g. /usr/lib/sendmail -bd -q1h) or by running ### /usr/lib/sendmail -q from crontab at appropriate intervals. Running ### sendmail in daemon mode is probably preferrable, since doing so ### will also handle mail that is mis-addressed to user@client. ### ### Originally From: rsalz@bbn.com (Rich Salz) ### Modified by: per@erix.ericsson.se (Per Hedeland) ###

## LOCAL CONFIGURATION INFORMATION

## Local domain name. ## This should only be changed if the full name of your hosts is something ## other than host.frobozz.com. Dmfrobozz.com

## The official name of this host. ## This may need changing if your 'hostname' command gives the full name, ## or you have specified the full name in your hosts database, or sendmail ## uses the name server directly (in a "default" Sun installation, none of ## these apply). To test this, give the command (after this file is ## installed) /usr/lib/sendmail -bs, and look at he hostname displayed. ## If the domain name is duplicated, remove the '.$m' from the definition. Dj$w.$m

## The server host where everything gets forwarded to. ## This is the one thing that you MUST change. Do NOT use a generic name ## like 'mailhost' here, but rather the name of the server host that ## should be visible in external mail. DRfrobozz

## Optionally do client-specific "aliasing" of certain local names. ## If you don't want mail sent to e.g. user 'root' on the client to be ## delivered to the same user on the server, uncomment the CL and DL ## lines below after editing them appropriately. ## (May be useful if groups of clients are administered by different ## individuals, since such mail often concerns host-specific issues.) # Local mail to these userids... #CLroot Postmaster MAILER-DAEMON # ...will be delivered to this userid on the server #DLsome-lsa

## GENERAL CONFIGURATION INFORMATION ## Stuff here is required and reflects some policy decisions.
