Tools Configuring Sendmail as a client only, how?
We are running sendmail-8.13.4 on AIX.

I need to update the configuration and make sendmail act as a relay client only, meaning it will only be used to send mail out of the host and NOT accept mail.

Here is my client.mc config:
Code:
include(`/usr/samples/tcpip/sendmail/m4/cf.m4')
VERSIONID(`sendmail config for aix7')
OSTYPE(`aixsample')dnl
MASQUERADE_AS(`myserver.com')dnl
FEATURE(`masquerade_envelope')dnl
FEATURE(`accept_unresolvable_domains')
FEATURE(`accept_unqualified_senders')
FEATURE(always_add_domain)dnl
FEATURE(`nullclient',`mail-relay.xxxx.myserver.com')dnl
define(`STATUS_FILE', `/etc/mail/statistics')dnl
define(`MAIL_HUB', `myserver.com.')dnl
define(`LOCAL_RELAY', `myserver.com.')dnl

We have an MS Exchange server, so we are basically using sendmail on a particular AIX host to forward all email to the exchange server and let Exchange handle everything.

The above configuration works fine for sending email to recipients using:
Code:
mail user@myserver.com

What I also need to do is be able to send the email with only specifying the alias part and not the domain, so if I do:
Code:
mail user

** sending email to userid, omitting the @myserver.com recipient domain part

I want sendmail to append the @myserver.com in this situation where a domain is not given. Is this possible without maintaining some sort of alias/list file for every possible userid > userid@mydomain.com?

Thanks.

mailstats

MAILSTATS(8)						      System Manager's Manual						      MAILSTATS(8)

NAME

       mailstats - display mail statistics

SYNOPSIS

       mailstats [-c] [-o] [-p] [-P] [-C cffile] [-f stfile]

DESCRIPTION

       The mailstats utility displays the current mail statistics.

       First,  the  time  at which statistics started being kept is displayed, in the format specified by ctime(3).  Then, the statistics for each
       mailer are displayed on a single line, each with the following white space separated fields:

	      M 	  The mailer number.
	      msgsfr	  Number of messages from the mailer.
	      bytes_from  Kbytes from the mailer.
	      msgsto	  Number of messages to the mailer.
	      bytes_to	  Kbytes to the mailer.
	      msgsrej	  Number of messages rejected.
	      msgsdis	  Number of messages discarded.
	      msgsqur	  Number of messages quarantined.
	      Mailer	  The name of the mailer.

       After this display, a line totaling the values for all of the mailers is displayed (preceded with a ``T''),  separated  from  the  previous
       information by a line containing only equals (``='') characters.  Another line preceded with a ``C'' lists the number of TCP connections.

       The options are as follows:

       -C     Read the specified file instead of the default sendmail configuration file.

       -c     Try to use submit.cf instead of the default sendmail configuration file.

       -f     Read the specified statistics file instead of the statistics file specified in the sendmail configuration file.

       -P     Output information in program-readable mode without clearing statistics.

       -p     Output information in program-readable mode and clear statistics.

       -o     Don't display the name of the mailer in the output.

       The mailstats utility exits 0 on success, and >0 if an error occurs.

FILES

       /etc/mail/sendmail.cf	The default sendmail configuration file.
       /var/lib/sendmail/statistics
				The default sendmail statistics file.
       /etc/mail/statistics	The symbolic link to the statistics file.
