I have an issue with some messages redirected from zimbra mailboxes over to Exchange server. The emails contain an excel spreadsheet. For testing purposes, I have had the originator of the messages send a CC copy directly to one of the exchange mailboxes I can open the message in zimbra, and the spr...

That document says "Note: The copied MDB file will *not* be a sparse file. It will be the actual size of the database." so I don't think it will help

but result is B TLS 1.3 No TLS 1.2 Yes TLS 1.1 Yes TLS 1.0 Yes SSL 3 No SSL 2 No If you did those steps and it still shows that 1.0 and 1.1 are available, it would suggest the connection is not hitting the proxy, or is hitting another proxy. Can you verify that the Proxy is enabled, either (a) enab...

Can you show the results of zmprov gcf zimbraSSLExcludeCipherSuites In our case we have zimbraSSLExcludeCipherSuites: SSL_RSA_WITH_RC4_128_MD5 zimbraSSLExcludeCipherSuites: SSL_RSA_WITH_RC4_128_SHA zimbraSSLExcludeCipherSuites: TLS_ECDHE_RSA_WITH_RC4_128_SHA zimbraSSLExcludeCipherSuites: TLS_RSA_WIT...

It is possible your server has been hacked

Have you looked at any of the emails to figure out what they are about?

Answering my own question in case anyone else has a similar requirement in future - NOTE: This is not an upgrade-safe modification.

I need to redirect all emails for certain mailboxes to a new external mailserver so they can be handled there. As a result, I do not want zimbra to add a standard domain disclaimer when it is forwarding them. I already have configured disclaimer for external only and that works as expected. What I n...

Perhaps you are running into the session limit for IMAP (if that is what they are using)? How many clients are connecting?
