Hi
We see a surge of deferred mails because of a proofpoint check resulting in mta
responses like:
Deferred - see https://ipcheck.proofpoint.com/?ip=[…]
The actual ipcheck on the mentioned domain does - on multiple tested ips -
return that nothing is blocked.
Is there a proofpoint representati
e list for blocking.
