Sending via secure SMTP suddenly stops working

[Per-Olof Litby]

Greetings,

I'm experiencing a strange problem with outgoing email via secure SMTP.
After working perfectly, suddenly I can't send mail any longer. Outlook
says that the SMTP server does not support SSL (don't have the exact
error message).

Usually, changing to another SMTP port number (I have two alternate
ports I can use) and rebooting fixes the problem.

This problem only appears with Outlook and Outlook Express - not with
any of the Mozilla mail clients, Mulberry, or Eudora.

Any ideas?

Outlook Express and Outlook only support secure smtp on the deprecated port
465. However, if you are running Outlook 2003 SP1, you can call Microsoft
Product Support Services and tell the SE that you are having a problem with
SMTP - SSL over a non-standard port. If the SE acts confused, ask them to
contact Greg Mansius (Microsoft Employee) and reiterate that it is a problem
with "SMTP - SSL over a non-standard port". This will clue Greg in real
fast to explain to the SE what you need.
