when my exim server receive a mail checks if both user and domain exist
(with a LDAP query) and then, if exist, sends the message to mailbox server
(getted from user-query to LDAP Server). Now i have a server of a costumer
(hosting) running Exchange.
I don't want (and customer too) to insert all the customer's users in LDAP
Server.
How can i route all mails directed to the domain mycustomerdomain.it to
their server without checking if users are local?
And how can i queue their messages if their server is down?
