I strongly suggest you study the mailbox_command in your configuration. If you have Procmail and it sounds you have it because you are on Ubuntu, you have to set this parameter first (it's absolutely mandatory to set) otherwise emails will not go anywhere.
Removing this parameter won't help, unless you remove entire Procmail.

The next option please, try setting your ISP's IP address in $mynetworks parameter and restart your posrfix. If it starts working then it will mean that either your ISP is not SASL authenticated or you have misconfigured your SASL. This simple test won't do any harm
