I am using Outlook without any problems what so ever.

It sounds to me like you are setting up Outlook to use port 465. In the
setup screen, set the port to either "25" or "587". I am using "587"
with "starttls" Your "incoming mail port" will depend on how you have
Dovecot configured. I use port "143" with "starttls" for Outlook. YMMV
depending on your configuration.

You might want to consider posting the output of "doveconf -a" and how
you have Outlook configured.
