Useless is a pretty strong word...it's merely a question of whether the benefit of the tool justifies the setup time. Much of my incoming mail is in response to enquiries I send out to trade suppliers and small businesses. If I implemented TMDA they would have to jump through hoops to get their response to me, it's difficult enough getting a response from some people anyway so I suspect that TMDA would reduce the reply rate to negligable proportions. The alternative of modifying the TDMA 'whitelist' when I send the enquiry out is similarly flawed (I have to jump through hoops) and anyway isn't guaranteed to work as they may not respond from an address I know about. Well, I'm not going to get too far into advocacy here, given that this is a MUA list and not a anti-spam software list, but I do need to point out that you must have read a very old version of TMDA's feature list, because it is much more than a simple whitelist (which you could do with a 3-4 line procmail recipe anyway). The situation you're talking about sounds like a good candidate for TMDA's date-keyed addresses. Only a very small proportion of my (wanted) incoming mail is from people/addresses that are known to me, a 'whitelist' would catch a tiny proportion of my mail. That depends very heavily on the robustness of the whitelist. Maybe TMDA isn't right for you...ok...but don't insinuate that it's just a pattern check against a file with a list of regexps in it. :) -- John Buttery Life is a whim of several billion cells to be you for a while.

All you really have to do is set your procmail rules so that mails with a score over 90 are sent to /dev/null, and mails with less are sent to your spam folder.

My adddress here is [EMAIL PROTECTED] and that's it, I don't *think* any alternatives are possible which will reach me here. The mail is not received via a POP3 server at all so 1) isn't applicable.

I think + addresses are the extension referred to above; have you tried them? I.e., [EMAIL PROTECTED] -- most modern SMTP servers will Do The Right Thing, and deliver it to the mailbox for user chris. Sendmail does it, so does postfix, qmail does it but uses a - instead of a + by default. I'm sure others do as well. Oh yeah, almost forgot -- only the MTA that invokes the MDA needs to support it.
