Sounds good, but as a poor s/w developer I leave that sort of thing to the network experts - I was just going to make some changes to qpsmtpd for now... > > That's why sending them a huge amount of text in return doesn't hurt that > > much, but choking their upload does. > > I think that depends how amply overprovisioned they are with bandwidth.

They might, but the more of their targets that we can get to do the same, the more it hurts them, so hence I'm suggesting changes to qpsmtpd so that anyone who wants to nobly tarpit a spammer can choose to do so, those who don't want to can tun the feature off (in fact, I'll probably make the default config value "do not tarpit", and then plugins etc. can freely decide to use it safe in the knowledge that it onlymakes a difference to those of us noble enough to turn it on). I'm not an ISP - just a schmuck on a cable connection, and I'm looking to annoy the buggers who spam me, as one of them has been joe-jobbing my (vanity) domain for 12 months now. I'm getting sick and tired of the 500-1000 joe-job bounces I get each day (I can filter them easily, but it still annoys me) so I figure it's time to waste their time in revenge. Cheers -- Tim
