Milter-greylist

Hi,

I am using v1.6 in fc3 linux.  It is working normally.
My question is: is there any way to config the
greylist at user's level, even partially?  Some users
ask me to put some domains in whitelist.  However, I
feel that it may not be good to whitelist these
domains to all users.  How to whitelist some specific
domains or some email-senders to some of my users, but
not to other users?

Thanks!

Harvey
