Rather than do this why not just lookup the addresses in Exchange via LDAP
lookups against Active Directory after handling the local accounts and
virtual domains?
This is what I do. My last two routers look like:
exchangeProxyAddressesLookup:
driver = redirect
data = ${lookup ldap {ldap:///CN=Users,DC=EXAMPLE,DC=com?mail?sub?(proxyAddresses=SMTP:${quote_ldap:$local_part}@${quote_ldap:$domain})}}
domains = dbm;/etc/exim/db/localdomains.db
verify_recipient
self = pass
pass_router = exchangeRoute
no_more
exchangeRoute:
driver = manualroute
transport = remote_smtp
route_data = ${lookup{$domain}dbm{/etc/exim/db/localdomains.db}}
where localdomains.db contains key/value pairs for the domain/ip address of
the exchange server it is routed to.
This also has the benefit of allowing me to reject bad addresses at SMTP
time rather than let exchange accept it and then try and relay a bounce
message back through the exim servers.
