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
noreply-dmarc-support@??? are bounced back to google, all other
dmarc reporting senders are allowed through.

Solution is to to turn OFF this switch.
