exchange - Recipient address rejected: Access denied

[sven2002]

hallo,

ein dringendes problem (seit heute):
exchange 2003 ereignis id 7004


Dies ist ein Fehlerprotokoll des SMTP-Protokolls für den virtuellen Server mit ID 1, Verbindung #670. Remotehost '195.3.86.156' hat auf den SMTP-Befehl 'rcpt' mit '554 <office@xyz.at>: Recipient address rejected: Access denied ' geantwortet. Der vollständige gesendete Befehl lautete 'RCPT TO:<office@xyz.at> '. Hierdurch wird die Verbindung wahrscheinlich fehlschlagen.

weiss jemand rat?

Error 554:

5.X.X Permanent Failure

A permanent failure is one which is not likely to be resolved by
resending the message in the current form. Some change to the
message or the destination must be made for successful delivery.

X.5.X Mail Delivery Protocol Status

The mail delivery protocol status codes report failures
involving the message delivery protocol. These failures
include the full range of problems resulting from
implementation errors or an unreliable connection. Mail
delivery protocol issues may be controlled by many parties
including the originating system, destination system, or
intermediate system administrators.

X.5.4 Invalid command arguments

A valid mail transaction protocol command was issued with
invalid arguments, either because the arguments were out of
range or represented unrecognized features. This is useful
only as a permanent error.

Wahrscheinlich mag er die Empfängeradresse office@xyz.at nicht.
