A long time ago someone helped me with setting up sendmail to simply queue and relay mail. They suggested:
1) edit /etc/sysconfig/sendmail and set "DAEMON=no" 2) edit /etc/mail/submit.mc and set FEATURE(`msp', `[IP.of.relayhost]')dnl
Given the sendmail-cf RPM is already installed a "service sendmail restart" is enough to a light, direct submitting sendmail setup.
How does one rewrite all mail to one specific address so it can be filtered by a user that receives all mail for this host? Can there be a rule in place with the above config? Hopefully that is just as easy in sendmail as it is postfix!
