Hi. I have an iPad 2 and a Mac Mini that aren't able to send or receive pictures. My wifi is restricted, and I need to know what website it is that apple iMessage uses to send its pictures so that I can submit it for approval.
iMessages are routed through Apple's servers, not a website. The address to the servers are not made public, so I don't think you'll have access to that information.
Hopefully this will help: Using FaceTime and iMessage behind a firewall
