Hi guys, I followed this tutorial http://library.linode.com/email/postfix ... .10-karmic and everything works, the only thing that i have changed was the follow line:

postconf -e 'mydestination = server.yourdomain.com, localhost, localhost.localdomain'

to:

postconf -e 'mydestination = localhost, localhost.localdomain'

I can send email locally:

mailx cunha@sergiocunha.com

And I can read locally:

mutt -f .

But I can't connect from a email client. I tryed with ssl, tls and plain (POP and IMAP) but nothing.

Here is my log :

Any help ?

From the guide referenced in your post, it seems more likely that you should log into dovecot using an email address rather than a standard username.

You're right !... SOLVED : ] Thanks !
