I have a custom program listening on port 25, but I still need to use
sendmail to actually send email from localhost to internet. I don't
know how to configure the sendmail.cf (Solaris 10 x86) to either
disable the listener or move it to a new port. You can see below that
when I fire-up sendmail, it takesover port 25...

sendmail.cf:
# SMTP daemon options
#O DaemonPortOptions=Name=MTA-v4, Family=inet
#O DaemonPortOptions=Name=MTA-v6, Family=inet6
#O DaemonPortOptions=Port=587, Name=MSA, M=E
OO Port=2525

# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

# svcadm enable smtp

In sendmail.mc you use to generate sendmail.cf insert the following lines:

FEATURE(`no_default_msa')dnl
DAEMON_OPTIONS(`Family=inet, Name=MSP-v4, Port=587, Addr=127.0.0.1')dnl
