Lorens, Thank you for the detailed reply. I'm interested to hear that some of the DNS smarts reside in postfix itself. As I had no luck with multiple records in the /etc/hosts file, I've gone to the DNS option and setup multiple A records for exchange.xxx.local, using that name in the Postfix's

Thanks for the advice. I don't use relay maps for the domain as the Internet doamin is shared betweent he MS Exchange server and the Postfix server. i.e I use MySql address lookups onthe Postfix server so it's easy to create addresses to forward email to different or multiple accounts. e.g sa...
