Whitelist/Blacklist from POP/IMAP Mail Client

Hi,

I see in System Settings -> Virtualmin Configuration -> Spam filtering options where these options exist:

Add senders of spam sent to spamtrap to blacklist? Global, Domain level, No
Add senders of non-spam sent to hamtrap to whitelist? Global, Domain level, No

However, I suspect that I do not want to enable either of these because they are system wide and will affect all domains. Further, at least on the primary domain, we have a pretty varied userbase and "one man's spam is another man's ham".

Is there a way to enable this functionality on a per-user basis?

I would like it if when a user forwards a message to spamtrap that the original sender is blacklisted in their own blacklist and similar for hamtrap.

Thanks in advance,

G
