[exim] Rewrite using encapsulated ldap query

Hello,

I have to do some rewriting using the ip address of the sending host
(namely the envelope from). Now there is a object class ipHost in nis
schema that would fit well to that issue but to get the correct value
for the rewrite I have to do another query with the content of the
manager attribute (which can also be empty).

I (think ;-) I know how to implement that by using one lookup inside of
another. Butis that safe if the manager attribute is empty or if the
inner query fails?

Regards
