I setup an account in Outlook and for the Pop3 and SMTP I gave it the
192.168.1.104 address and for user name tried "jan" as this is the name of
the mailbox I see in Postfix using Webmin and my PSWD and then told Outlook
to "Send & Receive" and it came back with an error that it couldn't find a
server to talk to. Does Postfix and / or Dovecot use ports other than the
standard 25 & 110?

How come Webmin doesn't have an Icon for looking at the Dovecot mailbox,
does it use the same mailbox that Postfix uses?
