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. All services worked fine after I performed the upgrade. 2 days later, I noticed that the zmmailboxdmgr service was down. I restarted Zimbra. A few days later, Zimbra was down again. Most times, the zmmailboxdm...

Blocking of IP addresses trying to login

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 ...

After the final migration, too late, I realized that there are now issues with CardDAV: The result is th...
