Howdy -- a few things to try... if you hadn't already, you may want to take a look at the email logs in /var/log/mail.log to see if any relevant errors are being generated.

You may also want to verify that you're using the correct username to log in with... the full username can be seeing by going into "Edit Users", and looking under the "IMAP Login" field.

Also, check that saslauthd is running, you may want to try restarting it.

Lastly, you may want to verify that for the ports you can't connect to at all, that there isn't a firewall blocking the port.

It looks like you're using Virtualmin GPL though, the area here is for folks using Virtualmin Pro. If you had any additional questions, we'd encourage you to use the Forums for support. We monitor the Forums, along with lots of wonderful folks in the community. Thanks!

in /etc/default/saslauthd

edited this line OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd" with OPTIONS="-r -c -m /var/spool/postfix/var/run/saslauthd"
