"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If it is blacklisted and your Anti-spam has that in it list this could vary well be the reason for emails bouncing back.

you said anti-spam (proof point) has that in the list? didn't get it

if proofpoint doesn't have the list , can email from that domain still be blocked

Your Anti-spam server gets updates from the internet. If it has been updated and has this domain in its list then that will casue it to flag this domain as spam.
