You don't have to use SMTP AUTH through the submission port. It is
common to offer AUTH on standard port 25.

No need for that either. Even I think poorly designed MUAs like OE can
not handle SMTPS.

Pleas read a howto for enabling SMTP AUTH running Sendmail, i.e.
following

http://www.joreybump.com/code/howto/smtpauth.html

Just note that the location of the TLS certificates changes with FC4
release. So if you offer STARTTLS to secure insecure AUTH mechanisms
LOGIN and PLAIN (Outlook and OE can't use secure MD5 mechanisms) - which
is highly recommended to be secured - make sure you define the propers
paths.
