An increasing number of mail servers are taking much needed measures to
deal with spam email, and I'm seeing some interesting bounces from the
majordomo lists which I administer. One of the more direct and effective
measures is for the mail server to look at the To: address in the header
body and reject mail for which the To: address is not local. Since
Majordomo always puts the list address in the To: header, this mail
bounces. Are there any solutions for this in the works?
The particular server whose automated response is shown below appears
especially clumsy in handling this, since the bounce notice was sent >to<
the To: address - definitely a no-no! Filtering at a per-user level based
on this header is, however, very effective at this point since most spam
email fakes this header. I use it for personal email filtering with
procmail, but have an exception list containing the names of all the
mailing lists to which I subscribe.
