I have to do a filter in the way that when an internal sender sends to a specific domain, the email goes to a specific mailbox.
email@example.com => firstname.lastname@example.org = email@example.com
BUT when firstname.lastname@example.org => email@example.com = deliver the email
I've already searched about postfix rewrite, but I don't understand how to do that.
Can somebody help me to do that with Zimbra ?
Thanks a lot for your help
