    It is only a small part of the solution. For example if you do not specify 'no default msa' feature it is not going to work.

    I find that to enable submission access on port 587 in sendmail, I need to ensure the following are both set in sendmail.mc:

    DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
    DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
    Then do:

    m4 sendmail.mc > sendmail.cf
    service sendmail restart
