    At this moment I am stuck in getting a Postfix -> Exchange relay config to
    work.

    Have switched on debugging in Postfix:
    In master.cf added -v as in: smtp unix - - n - - smtp -v

    Postfix does proper authentication:
    < 235 2.7.0 Authentication successful.

    Then I get this sequence:
    > MAIL FROM:<> SIZE=1270 BODY=8BITMIME AUTH=<>
    < 250 2.1.0 OK
    > RCPT TO:<> ORCPT=rfc822;newbie dot datapolish at gmail dot com
    < 250 2.1.5
    > DATA
    < 354 Start mail input; end with <CRLF>.<CRLF>
    > Hello world!
    > .
    > QUIT
    < 454 5.7.3 Client does not have permission to Send As this sender.

    I have been replaying this with telnet to find the offending item.
    It appears to be the AUTH=<> at the end of the MAIL FROM command.
    When I leave this out, or replace it with AUTH=<>,
    everything works fine.

    My problem now is to configure Postfix do the same!
    Do you have any suggestion?
    I have looked around quite a bit on the Internet, but alas!

    With kind regards,
