Hi,
We actually implement similar behavior in our fallback queues, which
is for remote servers that respond slowly or intermittently. The
method we used is in the Exim system filter, and is simple as this:
if error_message and not first_delivery and $message_age is above 7200
then
seen finish
endif
This will cause any error message (an NDR) that has had at least one
delivery attempt and is older than 2 hours to be discarded. You
can modify the 7200 if you like, this just makes sure we had two hours
of retries first. You can eliminate the check for message age if
you like.
You can find the location of your system filter by looking for the
"system_filter=PATH_NAME" entry in your Exim config file.
Keep in mind that code in the system filter is executed for _every_
message prior to _every_ delivery attempt, so be careful in this file.
Hope it helps some.
