Redirected message becomes corrupted

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

Re: Problems with TLSv1 1.1 and Ciphers (Zimbra 8.8.15)

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...

Re: Problems with TLSv1 1.1 and Ciphers (Zimbra 8.8.15)

Can we assume you did click the "clear cache" link underneath your server name on ssllabs - otherwise it will simply show you your previous results. What exactly do you mean when you say "Partly it does not work" I just used the first three commands $ zmprov mcf -zimbraReversePro...

Re: Send to multiple Address Email - Invalid Email Error

Aside from your regex test, have you done any other validation?

Have you tried a single email from the listed sender to the listed receiver?
Invalid recipient li.rocio@hotmail.com: 450 4.7.1 <senderaddr@prodest.es.gov.br>: Sender address rejected: 0

Re: Mail queue

It is possible your server has been hacked

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

Modify amavisd to not add disclaimer for one domain

Answering my own question in case anyone else has a similar requirement in future - NOTE: This is not an upgrade-safe modification. It will get overwritten if amavisd gets updated by a zimbra patch I added an extra check into the /opt/zimbra/common/sbin/amavisd code to look for the external domain b...

[SOLVED] Modify amavisd to not add disclaimer for one domain

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...

Re: Users randomly canr connect from email programs

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