[AMaViS-user] RBL Checks and secondary MX

[Reid F. <rfo...@ma...>]

I have a question regarding RBL checks with amavisd-new. I have =
amavisd-new,
SpamAssassin, and Postfix up and running fine on the primary mail =
gateway (mx
10). All RBL checks are working perfectly there. The problem is that a
significant portion of mail is being relayed through the secondary MX at =
the
ISP. When the secondary forwards its mail to the primary, the received =
header
shows the IP address of the secondary MX, which causes all RBL checks to =
be
useless.

Is there any way to force amavisd-new to "look further" at the received
headers so that it runs the RBL checks against the real sender's IP =
instead
of our secondary mail server?

I've searched the mail archives and google and come up with nothing so =
far.
Any help would be appreciated.
