[Dale Unruh]

Hello,

This week we have been getting several bounce email notifications for
different email addresses with the same domain name. Do you know what would
trigger this?

Thanks!

The attached message was received as a bounce, but either the bounce
format was not recognized, or no member addresses could be extracted
from it.  This mailing list has been configured to send all
unrecognized bounce messages to the list administrator(s).

*Weightmans LLP Mimecast Platform*
Notification - Message Bounce
*This is a notification message from the Mimecast email platform used by
Weightmans LLP.*

*This is a bounce notification message that an email you addressed to email
address andrew.roberts at weightmans.com <andrew.roberts at weightmans.com> could
not be accepted by Mimecast and therefore cannot be delivered to a
recipient at Weightmans LLP. *

The problem appears to be:
The message violated one or more content policies

list"] in BODY_TEXT, score is 6

If you sent the email to multiple recipients, you will receive one of these
messages for each one which failed, otherwise they have been accepted.
