We're about to launch out 11.08 GS install. The only remaining issue is that about 30% of the time, messages to our test group are delivered twice. Has anyone experienced similar behavior? Or do you have any ideas where I could look to further investigate this?
Thanks, -Matt
Hi Matt, The Postfix mail server should be keeping a record of who it sends the messages to. (I think the file is "/var/log/mail.log".) GroupServer delegates the delivery of Postfix, because delivering mail is a tricky thing that Postfix does it well. On the GroupServer side of things, people can have multiple addresses set as their “Preferred Delivery Address”. Visit the profile of the problem person, click “Change Email Settings” and check what they are. Kind regards, Michael
Hi Michael, I am able to catch duplicates going out about a third of the time in /var/log/mail.log Here's an example of the same message and it appears to be sent to postfix twice as there are 2 different id's 1463F97C890 and 0F84D97C88F. I've tested this out by repeatedly replying to the same message via email and the web based interface. It looks duplicates can occur no matter where the message originates from. Any ideas? Does it still look like this may be something internal with Postfix?

Hi Matt: Sorry to hear you're having duplicate message issues. Could you please email me that snippet from the log again (more if you can) directly? I'm following web-only at the moment which means I get the email addresses obscured (which makes it difficult to track) :-)
Thanks, --Richard
Just to update the record, this is fixed now -- there was a duplicate cron entry causing the spool to get processed twice in a bit of a race condition. --Richard
IS this fixed already?
Hi gleasonlia, Yes, the occasional duplicate messages issue has been fixed <http://groupserver.org/r/post/168ICYUPNZnSMMXrRD5tAw> Kind regards, Michael
