I can think of 3 ways to do it. (listed below in increasing order of
complexity)
1. Rename qmail-remote to qmail-remote.orig
write a shell script qmail-remote in /var/qmail/bin
#!/bin/sh
sender=$2
recipient=$3
grep -w $recipient /var/qmail/control/migratedusers.txt >/dev/null 2>&1
if [ $? -eq 0 ] ; then
exec /var/qmail/bin/qmail-remote.orig $newhost $sender $recipient
else
exec /var/qmail/bin/qmail/remote.orig $*
fi
copy the above shell script with execute permissions to /var/qmail/bin
after renaming original qmail-remote to qmail-remote.orig
2. Use moresmtproutes patch. Follow the discussion below
http://www.gossamer-threads.com/lists/qmail/users/137183
3. Use indimail from http://www.indimail.org. IndiMail can act as proxy for
multiple users located on different exchange servers (in fact any server
that supports smtp)
