    Hello Sanford S,

    Would you be able to have a sample of the emails being rejected to cloudfeedback@feedback-87.brightmail.com.

    Could you also confirm to which recipients are you trying to send the email to, so that I can locate the full logs.

    If you have any further concerns or queries please do not hesitate to contact us.

    Kind Regards

    Hello Stanford,

    Following the verification of the emails sent from cmginc.com to the recipient you provided, I couldn't find any new emails being blocked. During the past few days all emails have been delivered successfully, and also the detections that caused the initial set of fp's are no longer active(confirmed by our AS team).

    If you have any further concerns or queries please do not hesitate to contact us.
