[Greylist-users] Greylist with diffrent whitelists

[Sven Goran]

I am looking for a greylist milter that will allow me to add whitelist
entries for specific users.

For example:

User 1 wants to whitelist his friends mail address permanently.

User 2 doesn't want this. He instead wants to whitelist his company
server permanently.

etc..

Is there a milter that has this feature? Maybe connected to a MySQL db
or something similar?

Thankful for any advice on this matter.
