XFOR: Event 4123; Message Not Delivered When PR_AUTO_FORWARDED & Disable Auto Replies Set |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SYMPTOMS
A message sent from Exchange through the Internet Mail Service contains the
property PR_AUTO_FORWARDED but the value is set to False or 0. The Internet
Mail Service has the "Disable Auto Replies to the Internet" option
selected. This message generates the following event 4123 and the message
is dropped.
Event: 4123
Source: MSExchangeIMC
Description: A message passing through the Internet Mail Service has
been intentionally dropped. This is most likely an admin notification
(message describing mail failure), an out of office notification (OOF),
or an automatic reply from a user's mailbox. Dropping of OOF messages
and automatic replies is configurable in the admin pages. The gateway
must always drop notifications to the administrator, since they often
cause mail loops.
CAUSE
A third-party gateway may add the PR_AUTO_FORWARDED property per
documentation in the Microsoft Developer Network (MSDN). The message is
delivered into the Exchange system. If the message is replied to by a user
on Exchange and sent to an address that will be delivered through the
Internet Mail Service, the system acts on the message based on the
property's existence and not its value.
The WorldTalk gateway may add the PR_AUTO_FORWARDED property to messages.
RESOLUTION

version 5.5. For more information, please see the following article in the
