Hey Zhang,

Would it possible to give admin more control over amavisd policy in the future iredadmin-pro since you no longer supports cluebringer (I used to tune per-user/domain amavisd policy from cluebringer + patched amavisd)

Features I'm looking for is like to be able to turn-off virus-scanning (or bypass it at all for better performance) for certain user or domain (since some of my clients don't want to be scanned at all)
also to be able to allow certain user receiving the banned attachment, but still block others in general.

to improve performance, I suggest that bypass_*_checks is used instead of the *_lover (especially with the smtp-amavis_destination_recipient_limit = 1 in postfix setting)
