But if you return a code at the end that says [EMAIL PROTECTED] is invalid, but [EMAIL PROTECTED] is valid, have you really changed anything from when you failed it after RCPT TO? It doesn't seem that way. The spammers still know which addresses got through, and which ones were rejected and they can still clean their lists. _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
