I believe the hostname is more or less irrelevant, it is the domain name that 
matters here. You need to proper domain name

As for its being numeric, I believe the first character has to be a normal 
character, and after that numbers, characters and various other signs can 
follow

By the way, I suspect that a valid alternative here is to configure your 
postfix to use sonic.net as a relay, and authenticate to it. You might be 
sending emails with invalid domains then, but you'd be sending them to 
yourself, which I think they'll let you get away with

I also suspect that if you authenticate with the smtp server, you can bypass 
many of the other security restrictions. It's the way these things are 
normally configured
