Unable to deliver email to certain email address: 554 Denied [CS]

Hi,

we've noticed that we're unable to deliver an email to a particular email address, from some of our IP addresses.

The error message we see is "554 Denied [CS] [f59e9(some more random characters).mxlogic.net]


Is there some way to investigate why such an email was denied?

Thanks!

Charlie

Hello Charlie,

The message was denied because of a high spam score.

The following solutions are available.

For McAfee SaaS Customers, please do one or more of the following:

1. Place the sending domain on the User or Domain-Level allow list in the Control Console.  For instructions on how to do this, please refer to Adding to Domain-level Sender Allow List

2. Open a service request with McAfee SaaS Technical Support so we may investigate the cause of this issue and possibly reset the filter that is causing messages to be denied.

3. Send a copy of the message to SaaS_falsepositives@mcafeesubmissions.com. If the message was blocked, the sender can obtain a copy from their Sent Items folder.

For senders who are not McAfee SaaS Email Protection customers, please do one or more of the following:

1. Contact the intended recipient and ask them to add the sending address or domain to their allow list

2. Contact the intended recipient and ask them to open a service request with McAfee SaaS Technical Support so that the message can be reviewed as a false positive

3. Send a copy of the message with the original headers to SaaS_falsepositives@mcafeesubmissions.com
