Our webmaster sends out a monthly newsletter to thousands of recipients. Each month this results in hundreds of undeliverable messages.
The undeliverables are generally very helpful with why they were not delivered, account does not exist, SMTP problem, etc. I have tried setting up rules to filter on the body of the undeliverable in an attempt to better organize the mess but they do not work.
For example - If I set up a rule to look for the words 'account does not exist' in the body of the message and move it to a specific folder this results in maybe one or two messages being filtered when there are actually dozens.
I have tried moving the rule to the top of the list and not processing further rules with no success.
Does anyone have an idea on this?
