I agree with everything you said, except the smart people comment. If you tell me to login to my gmail account via web, and send and email to myself (from gmail to gmail) and use the successful delivery of the email as proof of port 25 being open, you have no idea what you're talking about. 

Guaranteed not using a DHCP address. Incoming port 25 works, outgoing fails to leave their network.

The first person I talked to thought the 24.x.x x addresses they gave me placed me in India. WTF?

Seven days, and this issue is still not resolved.
