Is there a way of testing for backscatter?
I do not believe that my setup up is a source of backscatter.
However, believing and knowing are different things.
As long as you reject messages destined for invalid recipients, and
don't accept-then-bounce messages with an after queue content
(antispam etc) filter, (ie, if you use on, tag it as spam, or
quarantine it, but do not bounce it), then you are not a source of
backscatter...
We work on the basis, that if we don't like it, we just drop it. On
our partner server bounce is sent to their postmaster, something I
would like to change. After all, if it smells like poison its usually
a bad idea to do a taste test.
In general, it is considered a very bad idea to 'drop' (or silently
discard) email once you have accepted it for final delivery. If you are
going to drop it, it is best to simply REJECT it.
But, your system, your rules...
