Anyone know what ports my firewall needs to have open for IMAP using the
"this server requires a SSL connection" option.

Looking in Outlook it shows the ports as SMTP at 25 and IMAP at 993. Okay I
know that IMAP is normally at port 143 unless you are using the SSL option.
But how is SMTP going to deal with the SSL requirement? I thought that the
port 25 would be dealt with by only postfix, and if that is true then I
guess Postfix is going to setup the SSL tunnel between the client and the
email server.

My goal is to have all email between the client and the machines encrypted.
Including there passwords/usernames as well. Is doing IMAP-SSL going to
accomplish this???

Also is there any other ports besides 25 and 993 that I need the email
server to have open..something im missing here?

Thanks,
Tom W.
