Hi list! I'm trying to configure Dovecot 2.2.18 to act as proxy. Dovecot has to authentificate the users against an LDAP-Server (AD) and then act as IMAP-Proxy to an Exchange Server. Now the problem is, that we have TWO Exchange servers (and two ADs, too). How can I say to Dovecot that it has to search for the user in the first AD (and if found proxy to the first Exchange server) and if the user was not found, to search in the second AD (and if found proxy to the second Exchange server)? Thanks a lot Luca Bertoncello (lucabert at lucabert.de)
