Hi, my emails to Support@CameraFTP.com are failing.  I get this.

Delivery to the following recipient failed permanently:

     Support@CameraFTP.com

Technical details of permanent failure:
read error

I then tried but I'm getting warnings on that one too.  Probably will fail too eventually:

Delivery to the following recipient has been delayed:

     Contact@CameraFTP.com

Message will be retried for 2 more day(s)

Technical details of temporary failure:
read error

Thanks!

Solved -  apparently the system didn't like that fact that I was using either an attached screenshot or including the billing email.
