This looks like something for SPF, provided the domains used do have TXT records. If you do have it running, and the domains do not have TXT records, then I don`t see any (easy) way of dealing with it other than custom spamassassin rules, like Sam said.
Some custom rules I made for spamassassin are working greatly against the more common spam like bank scams, fake phone and shop billings, but even though it reduces the spam even more, theres still those that I can`t filter or that are too bothersome to make a proper rule. Unfortunately I can`t block messages from proper mail marketing that customers consider spam and complain, since they are most likely the ones to have put their mail address everywhere in the internet. (actually I can block, but only after a request, and for that specific account/domain) Arthur Citando Sam Clippinger <[email protected]>: > I haven't seen much of this myself.
