[vchkpw] Mails delivered by maildirsmtp bounce with looping error after upgrade from 5.4.9 to 5.4.27
Hi all, First message to this list. We are running a setup in which a central server receives and sends mails for users sitting at multiple branches. Branches each have a server which downloads mails by fetchmail and uploads mails for users within our domains but sitting at other branches with maildirsmtp. Among different business units we have 6 domains configured on the central server. The central server is running qmail+vpopmail+qmail-scanner+spamassassin+clamav. The branch servers have qmail with local user accounts with courier imap. The setup has been running well with vpopmail 5.4.9 for past few years. Due to very heavy load on qmail-scanner we decided to implement John Simpson's validrcptto.cdb to filter out invalid recipients before messages hit qmail-scanner. As part of this we upgraded vpopmail to 5.4.27 in order to get the onchange functionality. The validrcptto mechanism now works perfectly. Now we can receive all mail from outside world ok, but any mail delivered to the central server with maildirsmtp from the branches bounces with mail is looping error. This must be because of the Delivered-To: header present in the message which was inserted by the branch server qmail while delivering the message to alias for onward delivery to the central server by means of maildirsmtp. What I would like to know is what changed between 5.4.9 to 5.4.27 to cause this. And how can I get this working in 5.4.27? Regards Koustubha Kale !DSPAM:49f05b0b32681232389314!

Now we can receive all mail from outside world ok, but any mail delivered to the central server with maildirsmtp from the branches bounces with mail is looping error.

Well, as I indicated above, your system is in no way a normal cluster. Because of this, and because of the sparse information provided, it's very difficult to determine what the problem might be. What I would like to know is what changed between 5.4.9 to 5.4.27 to cause this. And how can I get this working in 5.4.27? Well, technically you can look at the ChangeLog, but I'm not sure that will help your particular situation. If you put back the vdelivermail binary from 5.4.9, does it seem to 'work' again? More than likely, there was a bug fixed in the older version that allowed your odd system of clustering to work, whereas now, it's doing the correct checks and balances. Again, this is really only guess. I'd try putting your old vdelivermail binary in place and see if that resolves your issue. - -- /* Matt Brookings m...@inter7.com GnuPG Key D9414F70 Software developer Systems technician Inter7 Internet Technologies, Inc.

Sorry to top post, but what options did you configure 5.4.9 with and what did you configure 5.4.27 with? How do you determine what messages go to which branch? Via smtproutes? Forwards? Mx records? IP over Avian Carrier (IPoAC) ;) Regards, Tren - Original Message - From: Koustubha Kale kmk...@gmail.com To: vchkpw@inter7.com vchkpw@inter7.com Sent: Thu Apr 23 22:22:18 2009 Subject: Re: [vchkpw] Mails delivered by maildirsmtp bounce with looping error after upgrade from 5.4.9 to 5.4.27 Koustubha Kale wrote: The setup has been running well with vpopmail 5.4.9 for past few years.

After re-reading this, it may not be vpopmail's vdelivermail process rejecting the message. It may be a qmail process. Just something to think about. No, because just reverting back to vpopmail 5.4.9 solves the issue without touching qmail in any way. Its the combination of maildirsmtp and vpopmail 5.4.27 thats causing the trouble. Everything else is working fine. regards Koustubha Kale !DSPAM:49f14dc732688149620407!

Can you show the full headers from one mail from the Maildir on the central server. maildirsmtp removes the Delivered-To header from the mail before sending it to the destination host by SMTP. By any chance are there two Delivered-To: headers in your mail? here it is.
