[Solved] Is it possible to forward all outgoing messages from one mailbox to another?

Is it possible to forward all outgoing messages from one specific address to another with Carbonio CE?

I've tried several methods, but none of them worked.

1. Outgoing message filters in webmail settings work, but only if messages were sent from webmail.
   So it doesn't work if a customer uses Outlook, Thunderbird, etc.
2. Method from Zimbra forums via zimbraPrefBccAddress:

   zmprov ma messages_from@domain.ltd zimbraPrefBccAddress messages_to@domain.ltd

   Doesn't work.

3. I've found in Zextas config folder some postfix config, so I added code to /opt/zextras/conf/postfix_header_checks.in and after zmcontrol restart it appeared in /opt/zextras/conf/postfix_header_checks:

   #/filename=\"?(.*)\.()\"?$/
   # REJECT For security reasons we reject attachments of this type
   #/^\s*Content-(Disposition|Type).*name\s*=\s*"?(.+\.())"?\s*$/
   # REJECT Attachment type not allowed. File "$2" has the unacceptable extension "$3"
   /From: messages_from@domain.ltd/
   REDIRECT messages_to@domain.ltd

   Doesn't work either.
