[COLUG] Postfix or LDAP question

[Aaron Howard]

I have set up a "Postfix + MailScanner + SpamAssassin + ClamAV" SMTP
mail gateway for a customer of mine but have a question I hoped
somebody might be able to help me with.

Postfix is presently set to forward all mail destined for local
mailboxes to my customer's internal Exchange server and this works
fine.  The only issue is I have to have user accounts on the Postfix
box in order for it to think they're local before it will accept
e-mail from them.  That, in and of itself, is not so bad.  I can
easily create those user accounts on the Postfix box easily enough.

What I'd like, however, is to set it up so it will stay in sync with
the Exchange server.  That is, if they add a new user, I'd want the
Postfix box to see it.  If they delete a mailbox, same thing.

Is this more of an LDAP integration issue?

Any advice is appreciated.

Thanks,
-Aaron
