I've set a new rule to filter undelivered emails from System
Syntax follows steps 1> "With specific words in the subject"> "from
people or distribution list" > step 2 "Apply this rule after the
message arrives from System Administrator and with Undeliverable:
XXXXXXXX in the subject move it to the Email failures folder and stop
proecessing more rules
Where XXX text is omitted
Are these meant to deal with messages you are sending, or is this dealing
with spam messages coming in?
Either way, cut the rule down to a single trigger. Verify if it runs or
not by doing a run rules now and see if it moves the messages you feel it
should. Then, if it does move items, move them back, switch the rule to
the other trigger, and try firing it again. Try and see which particular
trigger point is the failure.
