Nice SMTP server is zmailer - http://www.zmailer.org - it supports WHOSON protocol (included in contrib part of distribution) which lets zmailer check WHOSON daemon for temporary authorized IPs to relay. You patch all aps to communicate IP to whosond so zmailer can check for them when unknown hosts try to relay. Patching is very simple - bare bones examples are 2 lines in one .c and modification of Makefile to include whoson files - included are patch for imap and radiusd. I patched cucipop to use whoson - it works nicely here for some time. Whoson is general solution which works via unix domain sockets, udp and tcp.
