Hay,
außerdem habe ich mal wegen dieses 2.6.0 nachgeforscht.
ZitatAlles anzeigenrfc3463:
X.6.XXX Message Content or Media Status
The message content or media status codes report failures
involving the content of the message. These codes report
failures due to translation, transcoding, or otherwise
unsupported message media. Message content or media issues are
under the control of both the sender and the receiver, both of
which must support a common set of supported content-types.
....
X.6.0 Other or undefined media error
Something about the content of a message caused it to be
considered undeliverable and the problem cannot be well
expressed with any of the other provided detail codes.
Dieses 2.6.0 Antwort-Handling scheint aber laut einigen Quellen ein Exchange-eigens Ding zu sein.
However 2.x.x ist immer "successful".
CU, Peter
