The above makes sense. However, if you were using an MTA such as
Postfix, you might want to put system-specific information into your
LDAP tree too. Then your approach might cause a superfluous amount of
lookups (poor performance if you host many domains).

Johan Vriesman (http://www.vriesman.tk/) has published a Postfix/Courier
IMAP solution. The idea is original; the English isn't terrific though
and it all needs some puzzling out, but take a look at it.
