In Cpanel/WHM there is a setting for Exim:
"Attachments: Filter messages with dangerous attachments"
If this is turned ON only Google delivered DMARC report messages from
[email protected] are bounced back to google, all other
dmarc reporting senders are allowed through.
Solution is to to turn OFF this switch.

Hi,

Is this a frozen message FROM my server outbound to google or a frozen

on my end? Or neither.
It's an outbound message FROM your server to
[email protected].
The message that triggered that message is 1bH6AS-0006lb-Ih (seen the

So, you server can't deliver the message to google and because this
message is a bounce itself, your server can't tell where to bounce the
bounce.
