sendmail.mc contains this option:
dnl # The following causes sendmail to additionally listen to port 465, ... dnl DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')dnl
However, when I enable SMTPS, sendmail stops listening on SMTP port 25.
If you have *both* lines for SMTP and SMTPS, then you should be OK. Are you sure it's not listening? Can you "netstat -leanp" to check? Perhaps your mail client is just refusing to do unencrypted SMTP if it sees the encrypted option available?
