Some gateways refuse to forward some messages issued by our site. This problem affects mostly BSMTP error messages. In the following example, some user at MIT.EDU sent a message to some user at our site (FRLRI61.BITNET). The local user name was wrong, so our mailer generated an error message back to the sender, an this message was rejected by CUNYVM. Could someone tell me why ? How does a gateway check the validity of some message ? Thanks a lot in advance. -- Roland Dirlewanger E-mail: rd@lri.fr Universite Paris Sud rd@lri.UUCP Laboratoire de Recherche en Informatique rd@FRLRI61.BITNET Batiment 490 Phone: +33 (1) 69 41 64 01 91405 Orsay Cedex -------------------- Here is the example: # Your mail was not delivered to some or all of its # intended recipients for the following reason(s): # # Validity check failed. # # --------------------RETURNED MAIL FILE-------------------- # Received: from FRLRI61(MAILER) by CUNYVM (Mailer R2.01) id 3865; # Fri, 02 Dec 88 11:11:13 EDT # From: MAILER-DAEMON@FRLRI61.BITNET # Received: by sun1.lri.fr, Fri, 2 Dec 88 16:58:16 +0100 # Date: Fri, 2 Dec 88 16:58:16 +0100 # Subject: Returned mail: User unknown # Message-Id: <8812021558.AB17631@sun1.lri.fr> # To: mailer@cunyvm # # ----- Transcript of session follows ----- # Connected to sun8: # >># RCPT To:<stephane@sun8> # <<< 550 <stephane@sun8>...
