Whom do you expect to send to your Sendmail host on port different than
25? Other unknown MTAs will not do so.
Some lines above your change you find another DAEMON_OPTIONS line in
sendmail.mc which instruction Sendmail to bind the MTA to localhost


Umm...I meant I would like to change the port that users send mail from...i.e. connect to the  server.  Is that not possible?  I was thinking port 587 for sending, but does that mean every server coming into my server has to know that?  I am running into the problem with roving users that have home ISPs that are blocking port 25 from their lines.  So, users have to go in and change their mail servers when they get home, then change back when back in the office.  Does that make a little more sense?
