Re: [Declude.JunkMail] Not supporting null originator Problem

Hi Chris,   Refusing null senders actually breaks your email server according to thr RFCs. I know it's nice to be able to block all the false returns caused by forging viruses, but doing so in this manner also blocks legitimate server responces.   rfc-ignorant.org is actually a good source of education.information on this and other email standards.   Bill ----- Original Message ----- From: Chris Anton To: Declude.JunkMail@declude.com Sent: Monday, December 19, 2005 7:55 AM Subject: [Declude.JunkMail] Not supporting null originator Problem Hi all... having a problem with a user sending to albertus.edu.  Getting following error from their server: Unknown user: [EMAIL PROTECTED]   RCPT TO generated following response: 554 Service unavailable; Sender address [EMAIL PROTECTED] blocked using dsn.rfc-ignorant.org; Not supporting null originator (DSN) 1) Is this a result of my "0 Null sender maximum tries"? Should I set this too 1 or too much spam threat? 2) Does this make me RFC Ignorant :-) 3) Should they really be blocking this email on such a flimsy test?   Thanks for your thoughts.   -Chris Anton --- [This E-mail was scanned for viruses by Declude EVA www.declude.com] --- This E-mail came from the Declude.JunkMail mailing list.
