Server Statistics graph with high MTA message count
Hello, we are using ZCS Network 7.1.2GA with 45 users and we have noticed high peaks in the mta_count graphs. The peaks occurs always at 7pm at night (people leave at 5PM, most users shutdown their desktops). A friend of mine using ZCS Open 6.0.8GA has a similar issue, he has 125 accounts and the mta_count goes as high as 14k at 12AM, 4AM when no one is in the office.
Is the MTA_COUNT graph accurate to measure sent/received messages or does it register all mta transactions?
Server Statistics graph with high MTA message count on Release 7.1.3_GA_3346.UBUNTU10
We are experiencing the same issue on our Zimbra e-mail server: Release 7.1.3_GA_3346.UBUNTU10_64 UBUNTU10_64 FOSS edition. Please see attached screenshot.
I already checked the logs such as /opt/zimbra/log/mailbox.log and /var/log/zimbra.log but I did not find anything unusual or questionable with respect to MTA relay. I also tested our Zimbra server for Open Relay and it passed all the test.
If there are anyone here from the VMware Zimbra team, please help us on this issue. If this is a bug, please let us know for any fix.
