Re: [exim] Fw: Reject Specific users...

Andreas,

Nice idea, but my Notes servers are firewalled off from my Exim server. I
don't have LDAP access to Domino. We are planning to push a flat file
extract from the NAB out to Exim for the look-ups.

Have Exim lookup each recipient in the Domino directory through LDAP.
Add this to your router.

    local_parts=\
    ldap; ldap:://dominoserver/?mail?\
    sub?(&\
           (|\
          (objectClass=inetOrgPerson)\
          (objectClass=dominoServerMailInDatabase)\
           )\
           (|\

(uid=$local_part)(cn=$local_part)(cn=$local_part@???)(mail=$local_part@???)\
           )\
        )

This should take care of aliases as well as mailin databases.
Make sure you replace yourdomain.com with your actual mail domain.
