Unable to Register Mailhost

[Phineas Fudrucker]

We recently upgraded our Proofpoint server and the names of the agents changed.  I dutifully updated the spamcop mailhost listing which worked for a month or so.  Lately, however, the parser is rejecting mails which pass through one of the Proofpoint agents.  I tried to update again but I am informed that:

The email sample you submitted for scarville@lereta.com
appears to traverse more than one domain.  
Please ensure that you configure each mailhost individually and in order.

The Proofpoint agents are named scapp04.lereta.net and scapp05.lereta.net whereas the MX is mx02.lereta.com so I guess the confusion is understandable.  How can I work around this?

We also have about 18 exchange servers though I am pretty sure only about three or four actually receive mail.  Will each one of these need to be validated separately?

Have you looked at " How do I configure Mailhosts for SpamCop? " down under How you will see there is an required order to update your mailhost

Yes I read that.  I sorta figured the software knew that RFC 1918 addresses are strictly internal.  I will keep plugging away at it.

I may have found a solution.  More accurately, I may have stumbled onto one.  I am not sure which attempts generated the desired result.

It also might take the email address in each received line and try to compare it.  If your ISP adds something like .local to the host that might be something that could make the parser think it is a completely different domain/email address.  Might be able to make sure that email is the same for every received line.

We can hope your solution works.

It seems to though I am not sure why.
