Exim bouncing to exchange

It would be nice, in general, if incoming SRS addresses were also
validated in the ACL in this way.

From the Exim 4 FAQ:
``Attached is an Exim 4 config file which is designed for an Exim server
that is put in front of an Exchange 5.5 system but which verifies the
valid addresses that are stored in Exchange via LDAP lookups against the
Exchange server.''
