Show logs from postfix and relevant part of configs – Lazy Badger Feb 29 '12 at 3:01
And read 1-st class docs, at least – Lazy Badger Feb 29 '12 at 3:07

SMTP authentication is not working properly. You have not enabled SMTP authentication in you outlook setting. If you have got the SASL authentication config part working properly from flurdy doc then it is only a problem with your outlook settings. This error happens only when you try to send to a domain other than the one you have used for your mail server. Sending local will work but not to other domains.

What I meant is can you check your outlook settings not the server settings. In the outlook outgoing server configuration you have to enable my server requires authentication. – proy Mar 6 '12 at 12:35
Out look then returns an error that says "your SMTP server does not recognize this type of authentication." it gave this error before and after SASL. – Nat45928 Mar 6 '12 at 19:31
In your smtp settings in outlook make sure it us using plain text authentication and SSL is disabled. – proy Mar 9 '12 at 13:13
