In Germany "GMX" is a well known and widely-used freemailer which offers
his users do activate spam-filters like for example "if mail has a From
XY@???, only accept it if it was send by an official
Yahoo-mail-server." Of course that can be applied to hotmail and others,
too.

Well, the point is that these Spam-filter are usually effective. So I
can see it on my own mail-server: some users have a forward from my
domain to gmx and of course Spam having a yahoo-From is not forwarded,
since gmx rejects that. So I generate a bounce, which can't be delivered
either, since usually the sender does not exist. It finally ends up in
my postmaster-mailbox.
I don't really care and have it filtered away if it is one of my "known
gmx-forwarders" and has the typical gmx-rejection. However, it seems
like some more sites my users forward start to reject Spam, which gets a
little bit troublesome, since my departments policy is to tag spam
(using SA) but not to block it.
