Hi Quanah,
I don't have a solid answer for you, as I've not implemented this for
amavisd-new, but maybe I can point you in the right direction. I modified some
existing Perl scripts that were originally intended to poll AD for a list of
accepted e-mail aliases to also get a list of accepted domains for Exchange.
Exchange stores a lot of its config in AD, so this wasn't too tough.
The list of accepted domains in an Exchange environment (at least for 2007) is
found at "CN=Accepted Domains,CN=Transport Settings,CN=[your exchange org
name],CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=i-worx,DC=ca". The
accepted domain object has an objectCategory of " msExchAcceptedDomain" and the
actual domain name is stored in the "msExchAcceptedDomainName" attribute of
that object.
For our Postfix purposes we pull the complete list of accepted domains
(extracting only their "msExchAcceptedDomainName" value, print that into a
file, postmap it, and give it to Postfix as its accepted domains list. The perl
script is cron'd to run every 15 minutes, as we don't want to bounce stuff
that's already being accepted on the Exchange side just because Postfix had not
yet been updated.
I don't know if that's useful to you as you were referring just to LDAP in
general rather than to an Exchange environment in particular, but hopefully
it's of some use.

Well, really all amavis needs to do is be able to query whether or not a
given domain should be considered local, rather than having a stored list
of domains.
