[Exim] several redirections with one lookup?

Hi all!

maybe you can help here... I'm a bit clueless by now :(

We are using LDAP for our user data.
I would like to add an ldap-attribute, that contains a reply-text and
another one, which states whether an auto-reply should be sent or not...

Is there any way to acomplish the above in one LDAP query? So that an ldap
query such as
ldap:///o=base?mailForwardingAddress,deliveryMode?sub?(uid=$local_part@$domain)

would
a) forward the address to the result of mailForwardingAddress and also send
out an autoreply if delivery-mode is TRUE ?

Thanks for you help in advance!!
