Changing outgoing relay to port 587
in [Sendmail]

Next: Would adding esmtp-msa mailer help? [was: Changing outgoing relay to port 587]
From: blueman on 14 May 2010 09:41 I just received a notification that Verizon will only accept incoming mail on port 587. I currently use my home Fedora 12 linux system to forward non-work outgoing emails to verizon while handling local emails and work emails separately, using the following mailertable entry: .mydomain esmtp:%1%0 .workdomain esmtp:work-address.com . esmtp:outgoing.verizon.net What changes do I need to make so that only the mail relayed to outgoing.verizon.net is sent out on port 587 while local emails (mydomain) and work emails (workdomain) still get handled as before? Again to be clear, I am *not* asking for my sendmail server to listen on port 587, I just want it to (selectively) relay on port 587 for certain hosts listed in my mailertable file. Note I have the following potentially relevant entries on my sendmail.mc file: FEATURE(`mailertable', `hash -o /etc/mail/mailertable.db')dnl DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl Thanks!

How do I send using an alternate port? http://www.sendmail.org/faq/section3#3.39

That was very helpful and it worked for my needs (well, I won't know for sure I guess until Verizon starts blocking port 25...). Still a question remains though. What if using mailtertable, I wanted to 'relay' some mail to port 587 and some mail to another non-25 port? Is it possible to set up multiple different relay mailers with different relay args specifying different ports?
