Hi, I'v successfully setup user@domain solution from http://www.howtoforge.com/forums/showthread.php?t=7880 I've added one more script to writeconf.php which produce smtpd_sender_login_maps (postfix table which i use to secure "From:" address - now there is no way to sent an email with faked "From:" address; only SASL authenticated owner of address can use his own "From:" address). After this i've enabled reject_sender_login_mismatch in postfix - now with user@domain login my mail server setup is closed to 100% complete -- GreetZ .:JbRaVo:.
