Thanks. I get the jist of what's going on here. Further, I see Remco, who initiated this thread, has a static ip, and perhaps a semi-permanent net connection, so running his own DNS is perhaps feasible. I, OTOH, am running a dialup networking connection, and running my own DNS would not be practical (or so I've been told). This canonifying of hostnames sounded exactly like what was going on, so I read RFC-821.2 and this is entirely consistent with what seems to be happening: ------------------------------------------------------------------------ Once the transmission channel is established, the SMTP-sender sends a MAIL command indicating the sender of the mail. If the SMTP-receiver can accept mail it responds with an OK reply. The SMTP-sender then sends a RCPT command identifying a recipient of the mail. If the SMTP-receiver can accept mail for that recipient it responds with an OK reply; if not, it responds with a reply rejecting that recipient (but not the whole mail transaction). ------------------------------------------------------------------------ However, this led me to wonder how I was able to send mail with bo for so long without problems. Initially, I thought my configuration must have changed, but recently I've realized that implementation of the latest anti-spam MTA features across the 'net roughly coincided with my hamm upgrade, thus it may not be my configuration that changed -- I'm not sure. At least this narrows the problem down to C_NAME lookup at my SMTP server send-time. Now all I have to figure out is how to alleviate that. -- David Stern ------------------------------------------------------------------ http://weber.u.washington.edu/~kotsya [EMAIL PROTECTED] -- E-mail the word "unsubscribe" to [EMAIL PROTECTED] TO UNSUBSCRIBE FROM THIS MAILING LIST.
