I've been doing some tracing on a problem that I discussed earlier. ================= To recap: mail from an MMDF site to user@foo.mydomain.edu gets source-routed to @mydomain.edu:user@foo.mydomain.edu after a domain name lookup fails. Since there is a mydomain.edu host, that's where it gets sent. I was a bit unclear at the time why sendmail 5.6.1 plus IDA 1.2.8 would not just bounce the mail back to the original sender as shown in the From: field. ================= After running etherfind on a session, I find out that the To: field inside the mail message has been rewritten to: user%foo.mydomain.edu@mmdfhost.mydomain.edu Oh well - my mail system says this goes to mmdfhost.mydomain.edu and sends the mail on to mmdfhost.mydomain.edu. The RCPT TO: command contains <user@foo.mydomain.edu>. The mmdfhost just bounces the mail back to mydomain.edu, since foo.mydomain.edu fails a domain name lookup. Repeat the cycle for 17 times and drop the mail. What can I do to fail the mail? Should I have PSEUDONYMS defined in the sendmail.m4 file as mydomain.edu? And unfortunately, I cannot follow the suggestion of the only person to mail a reply - calling for email terrorism ;-). Thanks for any help on this matter - /mde/
