I would recommend using this:
/etc/postfix/main.cf:
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
# Inbound relay for example.com. See STANDARD_CONFIGURATION_README.html
example.com relay:[mailhost.example.com]
# All other mail uses the smtp transport which has smtp_fallback_relay
# added to it in master.cf.
* smtp:[some.example.com]
/etc/postfix/master.cf:
smtp unix - - n - - smtp
-o smtp_fallback_relay=[other.example.com]
relay unix - - n - - smtp
Using different transports for inbound (relay) and outbound (smtp)
reduces congestion problems with the per-destination scheduler.
