At the same time, I am disabling TLSv1 and TLSv1.1 The documentation is here: https://wiki.zimbra.com/wiki/Enable_TLS1.3 I found that I also had to issue these commands: zmprov mcf -zimbraMailboxdSSLProtocol...

It seems like every update and patch I have seen in the past couple of years has had severe problems found by users in this forum. Before I update to 8.8.15 Patch 20, I would like to know if there is a way to submit a bug report to Zimbra support without purchasing the Network Edition. I did see a Z...

I want to know this too.

Oh my goodness, you are such a life saver. Thank you so much for posting this in the forum! I just upgraded a server 8.8.15 Patch 19 from Ubuntu 14.04 to 16.04 and then 18.04. All looked fine and I thought the upgrade was a success, then a couple of hours later, I got notifications that the disk spa...

I have this section in my zimbra crontab, but I didn't get an email recently when a customer's SSL cert had expired. We got no warning and no email. We do get the daily emails that come in a 11:30PM with the statistics of the messages received, sent, message sizes, etc. however. # SSL Certificate Ex...
