CentOS - Mar 2005 - Sendmail and port 587

Anybody know of a good doc for getting port 25 and 587 setup in sendmail/EL?

What I find seems to indicate that you can turn both on... but when I
do, 587 works, but 25 stops. I must be doing something wrong.

Best,
John Hinton

Odd. Both ought to work out of the box.

You can do one of two things:

1. Use the default submit.{mc,cf} files. Make sure the
    "no_default_msa" feature is NOT set in sendmail.mc.

2. Don''t use submit.cf. Set the "no_default_msa" feature in
    sendmail.{mc,cf} and define daemon options for listening on both
    ports, e.g.,

    DAEMON_OPTIONS(`Port=smtp, Name=MTA'')
    DAEMON_OPTIONS(`Port=submission, Name=MSA, M=E'')

I have a vague notion that the second option isn''t quite as good as
the first because the latter doesn''t do all the requisite MSA checks,
but I''ve never really explored it.

Beware of the second line in this form! It must be

DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea'')

Watch out for the litte "a" at the end of the mailer options. Else you
make your system an open relay.
