Hi,
For nearly 1/2 year now, we've been unable to receive emails from clients using higher-levels of symantec security. We had an issue last year with an infected machine that appears to have given us a negative reputation (Case 00013827), but we had this lifted late last year and we still don't receive emails.
Here's an example:

This issue is now happening with other clients who are using symantec products. We are unable to send/receive pretty much with everyone using your products. Can we get this resolved?
