Replacement of greylisting program.

hi all,

i have installed a SQLgrey which i need to be replaced
with better program which will parse the sender and
recipient address and do block or accept mails.

My primary intention is. can we replace a program here
and place new program which will reject mail from a
user or domain for whom they are subscribed not to
accept mails from certain domains. And Accept mails
from certain domains to certain recipients.

i like to build a whitelisting blacklisting like
amavis here at postfix level


Is anybody has this kind of program which handles the
situation as mentioned.

Like have any comments and suggestions.

Any replying words will greatly appreciated.

cheers,
Sunil.
