Valid email sent to group identified as SPAM and sent to Account Junk Folder

I have a group set up to accept email from external senders, and to forward the email to group members.  However, the email is coming in, then being directed to the junk folder of the administration account, and not going to the inbox of the that account or the testuser account (both legitimate mailboxes.)  What the heck is happening? 

Here's the trace information:

Sender: cxxxxxxy@gmail.com
