I didn't think of doing it that way... thanks (although I should have known to try it, since I already use domain only listings for mapping multiple domains into one). >Also, 'blacklist' will be interpreted as >a local account to which matching messages should be delivered. If you want >to reject or dispose of messages where the Return-Path matches, the entry >should be either: > >mx* = error >or >mx* = null Err, yeah, I knew that :-) I tend to type before I think, but I actually did know that it should be "error". >Either way, it's probably not such a good entry to actually use, though, as >the match pattern is far to broad. Yeah, I'm kind of torn. The spam is frequent and annoying, but I do realize that with that broad of a filter I run a serious risk of loosing legit email in the process. >You're aware, aren't you, that for the purposes of rejecting spam messages, >router entries like the above will only be applied to the Return-Paths of >incoming messages?

Yes, in this instance, the return-path always carries the distinctive marker of "mx##." in the domain part. I've actually been using that on a local client level filter for a while, but at the client level I can do much more specific filtering so I haven't noticed if anything will be caught with just "mx*" I also already have Verify Return Paths on to get rid of some spam and to enable other accounts to be routed to error (I have a few people who have specifically been blacklisted from sending email to my users). -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
