i get this spam whenever anyone sends a mail to @eukor.com and this list at the same time. i think that this kind of spam-bot sends to all recipients, not only to the person who sent it; but sends only if it sees @eukor.com in the TO: or CC: field. so, if anyone knows a similar "unsafeSpamBlocker", anyone of us might be able to disable one or both bots simply by sending a funny email (from a throw-away account because of side effects!!) to both email adresses - each twice to make it exponential. that would be the easiest pragmatic solution. sadly, i don't know any other unsafeSpamBlocker than this; it is years ago that i saw one. i guess they do not survive more than a few weeks – at least not without beeing blacklisted automatically. - marc Gesendet: Montag, 01.

They decided to use one of those obnoxious whitelisting systems that requires all senders to register with it before it will pass on their mail... but didn't exclude mailing lists from this. Mailing lists, of course, can't authenticate, so they're sending all these image-heavy "please whitelist yourself" messages in Korean to the list submission address *and* not seeing any actual list traffic.   This is one of the reasons I sometimes wish that use of an active spam whitelist like this were grounds for disabling the user's email account. They can't even tell what kind of mess they're making.  -- brandon s allbery kf8nh                               sine nomine associates allbery.b@gmail.com[allbery.b@gmail.com]                                  ballbery@sinenomine.net[ballbery@sinenomine.net] unix, openafs, kerberos, infrastructure, xmonad        http://sinenomine.net[http://sinenomine.net]
