Re: Email Relay Per Domain

Hi. You can not do this directly in ZCS through CLI or WebUI, it's been a RFE for years. You can do it in ZCS' postfix but you'll have to do it by hand and it won't survive updates. What I've done (and I'm not alone) is to create an outgoing relay (a tiny VM/VPS is enough) running postfix. I set up ...

Re: Sizing of innodb_buffer_pool_size

Hello Mark, I'm not really worrying about this. Let me try to explain how I came to this. I'm talking about a multi-servers setup, with SAN storage (no object storage).

Re: Sizing of innodb_buffer_pool_size

I did some test on a live server.
137 accounts, about 600 GB live data (store + index + DB + HSM).

Before
7.8G /opt/zimbra/db/data/
After
5.1G /opt/zimbra/db/data/

Re: Is anyone using an anti-spam gateway service?

UI bugs in 8.8.x

Hi all, we upgraded one server (8.6 to 8.8.8) and we're experiencing some UI issues, both on the webmail and admin side. The upgrade was done by using the export/import method (we changed of server). I'd like to know if other people see the same issues before opening bugs. Put a flag on some mails o...
