Before implementing Fluffy this was not a problem.

We have some users who are using an ISP for their e-
mail but put name@mydomain in their user information
and "reply to" rather then the name@isp.

These users have a mydomain mailbox on Exchange
5.5 that forwards their mail to a custom recipient which
is the mail box at their ISP.

The problem is that if name1@mydomain sends an e-
mail to name2@mydomain, when we try to forward the e-
mail to name2's ISP we are getting errors like :
"The Destination Server reported 501
name1@192.155.123.21 domain literals are not allowed"
or:
"The Destination Server reported 550. ISP requires a
valid sender domain from name1@192.155.123.21";

192.155.123.21 is the IP of the ISP mail server where
the e-mail originated from. They are catching on to the
fact that name1@mydomain actualy sent the mail from
the their ISP's IP.

Outside of the X Processing tag I do not see anything
significantly different in the header information og the e-
mails with or without Fluffy. Some where
name1@mydomain is being changed to name1@the
isp's IP?

This does not happen if I bypass Fluffy.

Why does it happen?

    look at the logs and see if the ISP is sending the Email for
    a IP that has no reversed lookup.
    The difference between exchange and Fuffly, is Fluffy deals
    with the Sending IP, Where excahnge deals with the Hello
    Domain name.

    In the header, you will see,
    Received: from mc-edc.com (unknown) [66.170.165.31]
    the mc-edc.com is from the hello the (unknown) is from
    fluffy saying there is not lookup for the IP.
    I believe Exchange uses the IP when this situation exists.

    Test 1
    User e-mail not spoofed
    Exchange 5.5 Proxied by Fluffy

    Test 2
    User e-mail spoofed
    Exchange 5.5 Proxied by Fluffy

    Test 3
    User e-mailed spoofed
    Exchange not Proxied by Fluffy

    Test 4
    User e-mail not spoofed
    Exchange not Proxied by Fluffy

    Here are the headers:
