    Hi all!

    I have this peculiar problem, and I've spent hours looking for a solution. I'm sure its very simple, yet it escapes me.

    I have a server, lets call it It has ispmanager and postfix installed. Postfix is configured through ispmanger to process mails from domains,, but not Mail for is served by third-party mail system (mx is set correctly to that 3rd party). Now what really happens is that sending & receiving mails to and from server2 or server3 - works, but if I sent mail from to - I get this error instantly (in Thunderbird):

    in logs:

    Now if I set in
    mydestination = localhost.$mydomain, localhost (eg. removing $myhostname)
    E-mail goes away, but all "normal" mails to & from server2 - are not coming.

    This has something to do with relay settings? :confused:

    Will be much obliged for any advice.

    Thank you!
