I'd like to implement per-user and/or per-domain mail filtering for users who do not use the web client. I found this item in the wiki:
Adding a disclaimer (altermime) or footer - ZimbraWiki
which I can probably adapt to my uses, though I hate the idea of spawning a script for every incoming email. It makes much more sense (to me, anyway) to check an LDAP entry and then decide whether to spawn a filtering script.
Does anyone have any suggestions? Is there a possibility that "server-side" mail filtering is being planned for a future release?
