Hi all, several attempts to contact Proofpoint through their suggested options
https://ipcheck.proofpoint.com/ [email protected] haven't been successfull unfortunately: Is there someone from Proofpoint here that can help us to get more information about what seems to be a prolonged listing of a large chunk of our IPs in about 4 IP ranges? (Oddly enough IPs are not tied to our mailing infrastructure). Any help in reaching out would be greatly appreciated. Michael Koestinger [email protected]
