Hi all,
any ideas how to address the following problem?
What happend:
one of our users created an mail rule in his mailbox, that does a forward of every new mail to an external address.
but he entered an invalid external address by mistake.
he received an email, the agent did the forward, but due to the wrong address he recevied delivery failure (wrong address)
but the delivery failure triggered the agent again …
Subject: how to stop mail loops caused by users that created a wrong forwarding rule
Same thing happened with us once upon a time. A few crashed servers and a few million dud email deletions later and all automatic mail forwarding were banned.
Methinks you wouldnt be the only one that would like a solution to this.
There should be a way around it. A rule that makes sure any error messages received are not forwarded. That should break the loop. Cover all error msgs, invalid Acc’s, full mail accounts, unreachable…
I figure only error messages cause loops - unless the recipient has a forward that forwards it back to the account, or to a 3rd, 4th, 5th… that eventually loops back to the original. But I doubt that eventuality can be covered… but then whats the likelyhood of that happening…!!!
