All,

This problem has been solved.   Thanks! to all who responded.  With a
combination of posts from this list as well as from comp.mail.sendmail and
[EMAIL PROTECTED], I've arrived at an acceptable solution.

Unlike other virus scanners, Norton works with a proxy and refuses to scan
any mail that does not use the standard SMTP and POP3 ports of 25/110. To
make matters more complicated, Outlook supports SSL over POP3 on port 995.
This means that Outlook and Norton AntiVirus are
mutually exclusive if POP3 SSL is desired.

Implementing another E-Mail virus scanner (e.g. McAfee, [even Avast
http://www.asw.cz/alwil.htm works better with SSL than Norton...]) allows
Outlook to retrieve POP3 over SSL and still catch any E-Mail borne virus.
Norton and Eudora 5.x are a compatible combination.  Then, setting up two
services (pop3 110 / pop3s 995) then allows either E-Mail client to retrieve
POP3 SSL mail while still maintaining E-Mail virus scanning capability.

Hope this series of posts helps anyone who may stumble upon this same
scenario in the future.
