Description John Eckerdal 2000-10-04 17:57:06 EDT
Updated sendmail to 8.11 (RedHat 7 version) and now sendmail listens on
port 587.
Why is that?
Since it is sendmail is linked to cyrus-sasl and OpenLDAP it might be
because of that.
(But then again - we do not use LDAP or SASL here).

It's the MSA service sendmail now provides.  Quoting the release notes:

        sendmail implements RFC 2476 (Message Submission), e.g., it can
                now listen on several different ports.  Use:
                O DaemonPortOptions=Name=MSA, Port=587, M=E
                to run a Message Submission Agent (MSA); this is turned
                on by default in m4-generated .cf files; it can be turned
                off with FEATURE(`no_default_msa').
