Following on from their success with Let's Encrypt (and certbot) the Electronic Frontier Foundation have launched an initiative to get all mail server using STARTTLS - if you don't know what it is nor why it's important then I'd suggest you read their FAQ.
Go to the EFF website, read what this is about and check your server: https://starttls-everywhere.org/
If you don't currently have any valid certificates on your server (i.e. you're still using the self-signed certificates from Zimbra) then I'd suggest you also read the great thread and instructions from Jim Dunphy in this thread: viewtopic.php?f=15&t=60781 - make sure you follow that thread and implement valid certificates on your server.
- Zimbra Collaboration 8.6 Patch 9 now available (includes fix for CVE-2017-8802). Read the announcement.
- Zimbra Collaboration 8.8.7 + Zimbra Connector for Outlook 8.8.7 are available.. Read the announcement.
- Are you a Zimbra Developer? You can find some interesting stuff in our Official GitHub: https://github.com/Zimbra and check the Community Projects too: https://github.com/Zimbra-Community/

Re: STARTTLS everywhere
It would help if Zimbra included setup of that in the admin UI.
