I must confess that I'm a little unsure what I really want...... My problem is that
95% of bounced mail, is typical doublebounce, where a user that don't exist anymore
(at my servers) has received mail and that bounce at my side. A spamer don't use a
correct address, so I then get the doublebounce back. Another problem I then get, is
the overview of "correct" bounces where there is a misspellings of some sort, that I
then could correct. Today I don't do this a 100%, since most of the "correct" bounce
mail drowns with the rest.
I can't see that I'm helping anybody with ignoring mail to non-existing (known) users.
I think I would be more help to my customers by getting the bounces down. Then again,
I can concentrate more on the issue about open relays, by have my users (that exist)
to report back to us about SPAM mail they have received. Here I can use some more
energy to block SPAM.
I'm not to found of having non-existing addresses in the lists out there, wasting my
(costly) bandwidth.
After we started to check against maps.vix.com and relays.orbs.org, the doublebounce
has gone down a little bit, but it's still to high. Anyway, I think we are on the
right track blocking traffic from known relays, even if I hate when persons tries to
make me do things, and I'm now in the situation trying to make other people to take
care and responsibility of their own mailservers ;)
