Well, my first thought is that you should lost the tendency to "Top
Post".

Second, why are you screwing around with the SMTP settings? Dovecot
could not care less about them.

Third, Outlook Express has been abandoned years ago. Why are you still
using it? If you really need it, try Windows Live Essentials
<http://windows.microsoft.com/en-US/windows-live/essentials-other-programs>.
I know users who have it working with Dovecot just fine.
