Not sure if this is the right category so please move it to where it ought to be if needed. I've got a client that's trying to get their mail through to one of their important clients. The important client just got an IronPort system (hardware appliance for blocking spam, etc.) and for the past 2-3 weeks has been blocking my client's email (low senderbase score, they're on Everyone.net). Both my client and their important client want the mail to get through to the end recipient, but initially, their IT contact says that there is no workaround for the senderbase score. I find that rather hard to believe, seeing as how it's just a firewall and would logically have a "first one gets it" sort of configuration for who to accept/block. If my client's email goes through a mail relay server at 22.214.171.124 (everyone.net) to get to their client, it blocks the email (the whole IP address has been blocked due to the low senderbase score). Is it possible to configure IronPort to make an exception for email from a domain name (domain.com) before the deny for 126.96.36.199? Any help would be greatly appreciated.
Thanks in advance!
