Hallo Forum,
wir haben das Problem dass wir bei bestimmten Emailadressen immer einen Zustellungsfehler bekommen!
sieht dann so aus:
Ihr Dokument: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
wurde nicht zugestellt an: XXXXXXXXXX@gmx.net
weil: host mx0.gmx.net[213.165.64.100] said: 550-5.7.1
tritt allerdings nicht nur bei GMX Adressen auf
Mails gehen über einen Domino Server raus,
bis letzte woche hat auch alles noch einwandfrei Funktioniert!
danke!
Martin
RFC 1893 - Enhanced Mail System Status Codes (http://www.ietf.org/rfc/rfc1893.txt)
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.7.X Security or Policy Status
The security or policy status codes report failures
involving policies such as per-recipient or per-host
filtering and cryptographic operations. Security and policy
status issues are assumed to be under the control of either
or both the sender and recipient. Both the sender and
recipient must permit the exchange of messages and arrange
the exchange of necessary keys and certificates for
cryptographic operations.
X.7.1 Delivery not authorized, message refused
The sender is not authorized to send to the destination.
This can be the result of per-host or per-recipient
filtering. This memo does not discuss the merits of any
such filtering, but provides a mechanism to report such.
This is useful only as a permanent error.
IMHO seid ihr auf einer Blacklist, sendet von einer dynamisch vergebenen IP-Range oder ähnliches.
