Jepp, that's right. > > Do you think this reject message will inhibit spammers to send you more > mail ? Hm, that is wild guessing. I think spamers dont want to waste bandwith, they want to get their mails read. If you silently delete the spam the spamer don't know if their mails get read or not. So they assume thei can send their mails again. If the spam get rejected they know that you don't accept the mail. It is up to the sending server to handle the rejection. Do they send spam again? Yes, I fear they see it as a kind of sport to get their spam trough. But doing nothing is no sollution. > > NOTE - the actual spamassassin/postfix/anomy method enables you to actually > get the Mail in, spamassassin checks it through spamc/spamd - and if it's > beeing detected a SPAM - you can tell the delivery script to delete it or > move it to a local-file for laer analysis ... > > Cheers > > Joerg > Martin -- ------------------------------------------------------------ H E L I X Gesellschaft f�r Software & Engineering mbH ------------------------------------------------------------ Hanauer Landstrasse 52 Telefon (069) 4789 35-30 D-60314 Frankfurt am Main Telefax (069) 4789 35-44 ------------------------------------------------------------ http://www.helix-gmbh.net [EMAIL PROTECTED] ------------------------------------------------------------
