Anyone know anything about bugzilla and postfix? I've got a system that I inherited, and then immediately had to move it to a new company / new domain, etc. Bugzilla has user accounts like "freda". I have an entry in /etc/aliases for fredA: freda: freddy.krueger at domain.com postfix is configured to relay to an exchange server (which handles the e-mail for domain.com). postfix also has an recipient_canonical file, which looks like: freda freddy.krueger at domain.com Things seem like they should be working - in fact, they kind of are... if I go to bugzilla, and ask it to e-mail freda his password the e-mail arrives in his inbox. However, if I log in as fredA, and update a bug, bugzilla hangs. The browser that submitted the update never gets a page refresh, and the bugzilla perl script hangs on the server. One difference is that in this case, it is trying to e--mail multiple addresses, instead of just one. The only clue that I can find is the following from the mail.log file: Jun 1 16:38:13 server postfix/smtpd[26483]: warning: non-SMTP command from server.domain.com[127.0.0.1]: X-Bugzilla-Reason: CC How can I further debug this? Thanks, Dan
