If you sent a lot of messages (say from [EMAIL PROTECTED], or webmaster) you would quickly realize that notification is worse. Every pc that has your address on a message in the inbox is likely to get a virus and send thousands of copies with your address forged as the From:. When any other system rejects with notification, you get it - and everyone who depends on you to keep their PC running will call you every time they get one of these... > The other thing that was totally amazing is how many spam filtering > solution there are that will accept a message, let the SMTP connection > close, and then scan/filter the email.

If you reject with an SMTP 5xx, you simply force the previous SMTP relay to do exactly the same thing. Unless it is the first hop doing the scanning, all you have is the forged header information to construct the error reply, and PC's almost always use a relay. --- Les Mikesell [EMAIL PROTECTED] _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
