>As far as I can remember the only things I have received that had Null >senders, aside from automated responses, were virii and spam!
I haven't heard of a single virus that uses the null sender, and only a very small percent of spam seems to. Yet, if you refuse mail from null senders, you violate the RFCs, get listed in http://www.rfc-ignorant.org (preventing you from mailing to some mail servers), you won't get any bounce messages, or DSNs. >There is no reason for the sending address not to be disclosed. Yes, there is. Read the RFCs, and you will see that some mail is REQUIRED not to have the sending address listed there. >I will ... filter Null senders from the mail scanner. That's your choice. However, be aware that that will cause other postmasters to receive "double bounces" and deal with your problem. They won't be happy about it, and may start using http://www.rfc-ignorant.org , blocking any E-mail you send to their domains. Is there a reason you don't want to receive bounce messages? -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
