Hi, A user of my server regularly faces issues when deleting messages from her iPad not being synced to the server. Interestingly, it only affects some delete operations. So new messages, read/unread marker changes are always reflected correctly. - She also uses an iPhone to connect to the Zimbra se...

Re: [Solved] zmmailboxdctl wont start

Thanks! I had a similar issue. Your analysis helped me to track it down to the root cause: In my case, port 80 was busy already. It turned out that the nginx service has been activated to start automatically. As a consequence, when Zimbra's Nginx service tried to initiate, port 80 was taken and zimb...

Re: Can not login to Ajax web client

I had the same issue that iPad users did not see content of the inbox anymore using the safari browser. After emptying the jetty work directory, the problem is fixed.

Issue after upgrade to 8.8.15 with zmfixperms

Hi, July 26, I upgraded from 8.8.11 to 8.8.15 on Ubuntu 16.04. The installation went well.

Blocking of IP addresses trying to login

I regularly face situations where some accounts change into a lockout mode due to external servers trying to login guessing passwords. While the lockout prevents the attacker to run many password attempts, the affected user is frustrated as he is not able to login anymore until his account is unlock...

Account lockout

Since a couple of weeks, one of my accounts regularly gets locked out. This is what I find in the logfiles (username, hostname and IP address obfuscated): content of audit.log: 2018-11-22 08:59:47,848 INFO [qtp66233253-35672:https:https://myserver.com:7073/service/admin/soap/] [name=user@myserver.co...

Zimbra 8.7.7 fast growing gc.log

Hi, I upgraded from 8.6 to 8.7.7 on Ubuntu 14. Since the upgrade, I notice a fast growing /opt/zimbra/log/gc.log file. The garbage collector reports every 2 seconds a line with stats. Within 48 hours, the gc.log file already became 2.2 MB in size. It does not seem to autorotate. So if not monitored ...
