All,
If there's anyone out there from Comcast's Email Administration or Abuse
dept, can you please contact me off list?
I've had a ticket open for over a week now and lets just say it's "being
dealt with poorly". 
TIA,
Hi Sean,
I'll connect you with our team. There is a thread looking for assistance at
your organization running for about that same amount of time. Bogon filters
are fun. -ren
