We currently have an SMTP relay provided by our webhost for around £200/year however I'm looking to move hosts due to our current host not being able to provide enough bandwidth to stream our new promotional video.

Does anyone else pay for an external relay? the school had it setup long before I joined, I'm considering setting up the SMTP service on our other site to relay for our domain then configuring it as our secondary MX - the chances of both servers/connections being down is minimal and they're on seperate exchanges.
