    Any mimecast users having issues with the anti-spoofing policy and Marketo email deliverability?

      We have been experiencing internal deliverability issues recently.  Marketo recently changed our IP range and didn't inform us.  Even after adding an exception to our anti-spoofing policy for the newly added IP range, we're still experiencing alerts and internal emails bouncing due to Mimecast's anti-spoofing policy.  There doesn't appear to be anything else we can do to fix the issue from our end. This has been ongoing for a couple weeks now and Marketo support has been slow to respond.  Has anyone else dealt with this recently and solved the issue?
