Try this:
On each of your client machines (not you mail server), set up the
sm-msp process to submit the e-mail directly to the sm-mta on your
mail server. This means you don't need to run a sm-mta process on
each of your client machines, and just the sm-msp process to check and
flush the queue occasionally.
In /etc/rc.conf
sendmail_msp_queue_enable="YES"
sendmail_enable="NO"
sendmail_outbound_enable="NO"
sendmail_submit_enable="NO"
In /etc/mail/submit.mc, modify the last line that says
FEATURE(`msp'... so that it directs the e-mail directly to the mail
submission port (587) on your mail server:
FEATURE(`msp', `[smtp.your.domain]', `MSA')dnl
The square brackets act to suppress the normal MX lookups sendmail
does --- usually you don't want that with this sort of mail submission
setup. Rebuild submit.cf and restart the sm-msp daemon:
# cd /et/mail
# make install-submit-cf
# make restart-mspq
Now, all new mail submissions should be routed through the central
mail server. You'll need to ensure the central server will handle the
mail for machines in your domain, which usually entails entering all
of the names of all your hosts into the /etc/mail/local-host-names
file.
Cheers,
Matthew
