Change the entry for domain.diffi.cult and .domain.diffi.cult in your
transport map to the MX for this domain:
domain.diffi.cult smtp:domain.diffi.cult
.domain.diffi.cult smtp:domain.diffi.cult
For myu...@domain.diffi.cult add a sender_dependent_relayhost_maps
(http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps)
in your main.cf and point your user to your exchange:
myu...@domain.diffi.cult smtp:[exchange.ser.ver]
