Would like to find out if spam/virus filtering works for distribution lists as well. I maintain a couple of mailing lists which get hammered with spam regularly but I'm able to filter them out as I'm currently using a mailing list manager for those lists. I'm considering moving that entire domain to my Zimbra server but itll be a no-go if all my mailing list users get a hundred-fold increase in spams overnight. Most of the users are from external domains so Zimbra's mailbox spam/AV filtering won't work for 'em.
If filtering does not apply to lists, alternatively how can I integrate a 3rd party mailing list manager with Zimbra?
