Time for the Bi-annual Domain-Spoofing Barrage

[MacMagus]

It seems to happen about twice each year... one of my domains is spoofed by a spammer for a few days and I get the bounce messages in my in-box.

Currently, I have a mail rule shuffling all emails for the domain (over a hundred today) into a folder and another mail rule coloring all of the bounce messages (by subject and sender, using "MAILER DAEMON" and postmaster@ and the like as criteria) so that I can casually look through it later to see if there's a legit email in the lot.

Has anyone come up with a better tactic for dealing with this crud?

Oops! I just noticed that I used the wrong word. I meant "bi-annual," not "biennial."

I humbly offer my apologies to the community.

Edit2: Cool! I can still edit the subject line of the original post!

I got it Thursday night/most of Friday. Filters in my mail browser catch it but my webmail was out of control.
It was almost all to one particular address at the "bad" domain.

And to answer your question-- I really think your filters are the best approach.
You don't want to think about what some pencil-nosed geek at your ISP might screw up for you trying to handle it on their end.
