mydebianpostfix

I have one server set up with newest postfix,dovecot,imap,,mysql-server and mutt if that matters

Its local user is called "administrator", the local hostname "mydebian" and the dns "example.org"
It currently has two mailboxes: "[email protected]" and "[email protected]"

- When trying to send mail from one account to the other (with mutt),
it says that the mail was sent by "[email protected]"

- When trying to send mail destinated outside local net, for example to google mail,
same thing happens

- When trying to send mail from google mail to any of the accounts at "@example.org",
google tells me the following:

----------------------------------------------------------------------------
Delivery to the following recipient failed permanently:

    test@example.org

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain.
We recommend contacting the other email provider for further information about the
cause of this error. The error that the other server returned was:
550 550 5.7.1 Unable to relay (state 14).
----------------------------------------------------------------------------

- Below are some logs/useful information

example.org mail is handled by 10 mail.example.org.
