I had this issue too on a customer multi-servers setup. The two LDAPs were out of sync. If the MTA server was asking the "correct" LDAP (the one that handled the MTA upgrade fro 8.6 to 8.8), everything was ok. If it was asking the wrong LDAP (that was not aware of the upgrade because out o...

Hello.

I'm hitting the problem too (8.8.12P3).

Did someone opened a case to Zimbra's support?
I saw nothing in the bugzilla (yet).

It's quite difficult to force the users to use a pre-defined folder order and forbid them to use another one.

This is the case for all "patches", there's only patch one version and an OSE patched system appears as NETWORK.

Zimbra/Synacor is very aware of it.

You have to host your files elsewhere (on a web server) and include them as HTML in the signature.

The domain cert you're using only works in nginx, not postfix (there are several threads on this). If you want to "fix" this the easiest way is to use a single certificate based on a CSR that includes all the FQDN you want. You might want to check the last Let'sEncrypt tool for ZCS, as it ...

If you do that, you'll delete the BLOB (the file on the server) while the rest of the system (database containing the list of messages per user) will not be aware of it. For the system (IMAP, POP, webmail), the message will still exist but as the file won't be here any more you'll get "missing ...
