Sorry if this is answered before. The situation is I installed zimbra server, and everything is cool, but I need mails from the other domain NEVER marked as SPAMs, because the other domain is a branch office and my boss may get angry at anytime if he keep finding branch office mails from his junk folder...
So my simple thought is if I can set that domain as a trusted domain, like an exception from SPAM checking, that will be good. But so far I didn't find that option in admin interface.
Any ideas? Thanks in advance.
