Having from over from iPlanet, there was a feature I used to use that involved global sieve rules that applied to all users. Basically, it was "write once, apply to all incoming messages". So I wrote one that handled all mail flagged with the [BULK] tag by our Barracuda spam firewall and dropped it into a folder called Bulkmail in any of the recipient mailboxes. Is there an easy way to dulplicate this functionality on Zimbra? Or do I have to apply a sieve rule to each user on the server?
