Courier is a drop in replacement for qmail, and does non-existent-address rejection before accept - it threw over 90,000 bounces on the floor for me a few weeks ago, when some spambag in the states sent out mail with <some-random-text>@katipo.co.nz in the From: line.
The must have also set the envelope to <some-random-text>@katipo.co.nz for you to get bounces (al la DSN). If you are being smurfed, you want to dump things during the SMTP conversation if possible. Its been a long time since I had to deal with that, at the time it was in the sendmail says and I just hacked S98 to to it (I think, this was years ago literally). These days, there are much nicer ways of doing this, sendmail has something (dunno what) and postfix has several effective mechanisms which I use (mostly because I host a number of domains, none of which have webmaster@ or other common names, so to avoid spam I only accept mail for a few specific addresses and drop the rest). --cw --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
