Hi Jeff,

you are right. This means that spam was accepted by our relays. These spam
mails are coming from MTAs operated by spammers. Most of the ip addresses
can be identified by sbl.spamhaus.org. Unfortunately, in Germany you are
not allowed to generally block MTAs. This has to be the decision of the
end user.

My comment was, we do not have to make the regex more complicated if all
what we get is faster spam acceptance.
