Hi,
With all this discussion on how to and not to take care of legal
bounces, be they wanted or not...
How do you people take care of legal bounces that really are erronous?
What do I mean?
At one of our domains we get a lot of SPAM, thats relatively easily
handled with all the filters and software
available today, but one thing we are plagued with is bounces from spam
sent to other domains using our
domains users as faked senders... these will not be caught in our spam
engines and are really erronous since
none of our accounts was the really sending these emails... but we sure
do get the bounces...
How do you people sort these out?
We are really not interested in bounces and rejects because of mail WE
did not send.
This is called backscatter. now that you have the name, you can google :)
- the backscatter readme has some ideas that you can use.
- spamassassin has a vbounce module.
- if at loss, you can tag envelope sender addresses and only accept
bounces to the tagged addresses. (here, there is no need to go for BATV.
just use address extensions).
- you can use backscatterer.org list. beware though. it also lists SAV
(CBV) sources.
