Re: HTTP ERROR 502 Problem accessing ZCS upstream server

502 errors mean the proxy service can’t talk to the mailbox service.

Please take a look in the mailbox log as well as zimbra.log and post what you find.

Re: Upgrade from 8.8.8p6 to 8.8.9 failed

If you have a Network Edition system you can use to access the Support Portal and file a bug report, please do so once you are ready. If not, please post the results of your discovery and I can do the same. Zimbra have committed to me that they do monitor these forums for important bugs impacting mu...

Re: Upgrade from 8.8.8p6 to 8.8.9 failed

Hi, just a quick heads up: I just tried to upgrade our first 8.8.8 test system to 8.8.9 (based on Ubuntu 16.04) and it failed due to a package conflict. The install.log says ... same here on RHEL/CentOS 7.x The upgrade failed with RPM dependency errors: error: Failed dependencies: zimbra-common-cor...

Re: Old topic but, Zimbra never learns

My Tag/Kill are set to 75/33 respectively <snip> Bill, I think you mean Kill at 75 and Tag at 33? :-) FWIW I've found I can go to 75/20 with few false positives (legitimate email incorrectly tagged as spam). Tag values above 25 with users whose emails are very public, e.g. listed as contacts on com...

Re: [Solved] InnoDB: Assertion

Disaster Recovery strategies always have a cost:benefit:risk:likelihood matrix around them that different folks in a company will weight differently. The worst Zimbra disaster I ever came across was a 450-mailbox server where the sysadmins had run the installer a few times as part of an attempted up...

Re: mta in - mta out

I just reread your original message and I confess I don’t understand how you are able to receive third-party inbound emails from the Internet if you require authentication on port 25. I also think the simplest solution is to get your MUA users simply to use the correct port. Maybe I am missing somet...

Re: mta in - mta out

It’s possible I am not understanding your question fully, but basically: 1. Postfix on port 25 is configured to do no authentication and to deliver email only to domains on the Zimbra server. 2. Postfix on ports 465/587 will deliver mail anywhere, to any domain, provided the sender authenticates. 3....

Re: [Solved] InnoDB: Assertion

Well that's good fortune there for sure! Not sure if you know about it, but for 8.7 and earlier, if you enable MariaDB Binary Logging (you need some disk space for this for sure), then you can do: zmlocalconfig -e mysql_backup_retention=8 which will cause Zimbra to run nightly MySQL dumps as part th...

Re: InnoDB: Assertion

Not at all sure this would work, but can you export the mailbox, then delete it, then recreate it and import the backed up tgz file? The user I expect cares less about the state of MariaDB and more about their email (and I also expect I'm telling you something you already know as well! :-) ) But per...
