Add this to your sendmail.cf and it will tell you what your mailer
thinks the destination address is when it receives a message:

#############################
###   Format of headers   ###
#############################

...

HReceived: $?sfrom $s $.by $j ($v/$V)
	id $i for $u; $b

...

$u is the recipient user.  If mail is rerouted and is returned to you,
you'll be able to tell which machine changed the recipient.
