Postscreen is successfully blocking a lot of spam for us. Our DNSBL

163.com as their service provider. Of course this is being
blocked. I do NOT want to allow 163.com as a whole to be
whitelisted (I'm getting 100s of connections/day from them and AFAIK
only this particular address is sending legit email.)
Is there anyway to have postscreen allow just the one particular
address?
postscreen knows the client IP address, nothing else. If the
customer uses a particular IP address, you can whitelist it in
postscreen_access_list.

The alternative is to move the offending setting from postscreen to
smtpd_sender_restrictions where you can whitelist by sender or
client name.

That is what I thought. However, postscreen DOES have that information
eventually as it logs the reject with sender and recipient.
