I'm using Amavis + SpamAssassin + Clamav for incoming mail filtering.  Being able to check quarantined messages is great,
but it would really be helpful if I was able to deliver a message straight to a local mailbox when viewing it in quarantine.
For example, if a message was classified (incorrectly) as spam, I'd like to be able to copy it directly to a local mailbox
I have called validtrap (a cron job feeds all the messages in that box to sa-learn as ham each night).

Just a suggestion.
