in real world, postfix mostly is setup as incoming and/or outgoing smtp relayserver for exchange by high performance and cheap and best spam and antivirus filtering, postfix normally needs the valid recipient mail addresses ( and domains ) from the ad to to this job ( or at minimum address recipient validation), there are serveral strategies to make this kind of setup work, which does best, depends i.e on your local network setup, look google for examples how to use postfix relay with exchange if you wanna get off in total from exchange, without loosing groupware functions of exchange search for alternatives ( free and paid ) like kolab etc you may also use postfix/dovecot/horde/spamassassin/clamav to implement a free alternative to exchange ( if youre good you get a nearly cross platform working mail groupware alternative up to 90 % of the exchange features at last learn difference between smtp , pop3, imap, mapi, http etc and if you want to understand what are differences between exchange and others you should understand exchange and outlook first too, which is more difficult then clicking wizards on guis , this will give you the needed basics for make decisions -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
