[Exim] Verify recipient against LDAP

Hi all,

I'm working a config for an Exim 4.10 server, the basic idea is that after
the rcpt to: the Exim server checks to see if the email address is valid by
querying an LDAP database. The email won't be delivered locally on the Exim
server but forwarded onto another server, all I'm doing is checking the
recipient is valid. I'm pretty sure this is possible, but can't work out
how. Does anyone have any idea's?



Cheers
