RE : Vacation problem
Here's the problem: $ telnet mail.intellinetinc.com smtp Trying 139.142.54.37... Connected to h139-142-54-37.gtcust.grouptelecom.net.

You don't want an auto-generated message generating a bounce message, since that could lead to an infinite loop. Thus, just like mailer-daemon messages in the MTA, a vacation message should have the envelope from set to . -- John A.

It is hard to tell from the logs since you are using 4 different email addresses, but it looks like sieve tried to send mail from (which sendmail accepted, but gave an authentication warning since cyrus isn't listed as a trusted user in your sendmail.cf file) to [EMAIL PROTECTED] That gets sent, apparently to the same MTA, which then has a problem talking to the relay mail.montana-education.ab.ca. It then tries to send it to [EMAIL PROTECTED] (presumably an alias from postmaster), and again has a problem talking to mail.intellinetinc.com and panics since it has nowhere to send the bounce message. So, it looks like Cyrus is fine but your MTA is misconfigured. -- John A. Tamplin Unix System Administrator Emory University, School of Public Health +1 404/727-9931

So, it looks like Cyrus is fine but your MTA is misconfigured. I did some code change in lmtpd.c in function send_response (line 872): I changed smbuf[3] = ; to smbuf[3] = [EMAIL PROTECTED]; And it worked fine. Assuming that, I think the problem is in MTA (Sendmail in my case) configuration. BUT I didn't configured my sendmail to refuse empty Return-Path: I suspect Sendmail is configured to do that by default. And I'm sure there are thousands MTAs doing the same thing (let's say to reject spam messages using empty Return-Path) I'm not sure whose problem is that, cyrus or MTA but by defaulf installation (and wothout some code change in lmtpd.c) it simply does'n work!
