I am having some issues configuring outlook to work with postfix / dovecot.
I can receive mail to the domain but cannot send.
I have done the following:
email account setup using the following:
Incoming mail server: mail.domain.com
outgoing mail server: mail.domain.com
More Settings: Outgoing Server
Test results say: Completed
However when sending mail I get:
The following recipient(s) cannot be reached:
'firstname.lastname@example.org' on 8/15/2012 7:10 PM
554 5.7.1 <email@example.com>: Relay access denied
Now with the "My outgoing server (SMTP) requires authentication checked with "Use the same settings......" checked the test asks for my credentials which I have tried both username and firstname.lastname@example.org
