Phineas Fudrucker Posted April 22, 2020 Share Posted April 22, 2020 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?

Lking Posted April 22, 2020 Share Posted April 22, 2020 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 https://www.spamcop.net/fom-serve/cache/397.html Quote Link to comment Share on other sites More sharing options...
Phineas Fudrucker Posted April 22, 2020 Author Share Posted April 22, 2020 Yes I read that. I sorta figured the software knew that RFC 1918 addresses are strictly internal. I will keep plugging away at it. Quote Link to comment Share on other sites More sharing options...
Phineas Fudrucker Posted April 23, 2020 Author Share Posted April 23, 2020 (edited) I may have found a solution. More accurately, I may have stumbled onto one. I am not sure which attempts generated the desired result. Edited April 23, 2020 by Phineas Fudrucker spelling, grammar Quote Link to comment Share on other sites More sharing options...

How can I work around this? 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. On 4/23/2020 at 10:53 AM, Phineas Fudrucker said: I may have found a solution. We can hope your solution works.
