I am assuming his MTA is using LDAP as the backend for the virtual map
for exim..As that is what I use in my setup with postfix using LDAP as
the backend for the virtual delivery table map. 
He still needs to escape the @ in whatever he has exim configured to use
to map the user at dom.com so it will be mailed to
user\\\@dom.com at mailserver.host.name when it is delivered to LMTP.
