Just to understand, I used "courier" before "dovecot" (by following your tutorial on ubuntu). Courier used SSL for secured connection instead of TLS with Dovecot right?
TLS is SSL for imap connections,so courier and dovecot offer both the same encrypted and unencrypted connection methods to ecxernal mail clients.

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