1. Why does it happen to web2 but not web1?
Web1 and mail1 are in the same network.
550s usually mean relay access denied, sounds to me like it doesnt want to relay mail for external addresses, are you using an authentication mechanism such as sasl for relay access? Whats in your postfix conf in particular concerning relay access, smtp sender and recipient restrictions etc?
