Sasl not installed??

TLS is SSL for imap connections,so courier and dovecot offer both the same encrypted and unencrypted connection methods to ecxernal mail clients.

Understood. I asked that cause with Outlook when you create an account it detects the server configuration, and since I used Dovecot detection fails on secured connection. But I can configure it manually... So, I think the problem is Outlook?

This means that this hostname does not exist. If you send something to a address that does not exist, it will never arrive there.

So, it is not on my side, right? or can I do something to solve that?
