mailserv/mailserv — Issue #10: Whitelist earlier in SMTP conversation?

I've got some incoming emails bouncing because they don't have reverse DNS set, so they get rejected like this:

Nov 2 23:18:30 mail postfix/smtpd[24054]: NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 450 4.7.1 Client host rejected: cannot find your hostname, [x.x.x.x]; from= to= proto=ESMTP helo=

I want to receive these, but If I put the IP or name of this server in my whitelist, they still get rejected. Can that be fixed by checking the whitelist earlier? Some other way?
