We've got sendmail mail working on one server in daemon mode via
both ports 25 & 465. It works with all our email clients doing
STARTTLS
and authentication. We have another server that we HAVE to run
sendmail
through inetd (don't ask why, it is just so). Via inetd, sendmail is
started with the command:

sendmail -bs -Am

This works fine for all port 25 traffic. We have email clients such
as Netscape, Eudora, and Outlook that work fine on this port.
However, we have some outside users that can not connect via port 25
because their ISP's block this port, so we tried an alternate port,
465.
Well both Eudora and Outlook expect an immediate TLS connection
WITHOUT using the STARTTLS command for any port other than 25.
Is there a command line option I could use to force sendmail into
the TLS mode? Is there any other way other than the command line to
do this? Any would be greatly apreciated. Thanks.

It sounds like you may not really need / want the STARTTLS support for
out side clients. If this is the case, consider the MSA port (587) for
your clients to send email in on.

Does anyone have any ideas on how I can force
sendmail into TLS mode? A command line option or
a sendmail.mc or sendmail.cf option? Anyone have
any ideas? I've really got to get this working
outside of daemon mode. Any would be greatly
apreciated. Thanks.

I guess what you want is the M=s modifier (run SMTPS) for
DaemonPortOptions, but applied when running 'sendmail -bs'. I *think*
there should be a way to achieve that, but the amount of time I was
willing to spend digging through the source and experimenting ran out
before I could come up with the answer.:-) However, this is exactly what
'stunnel' is for - try it.
