You seem t ohave misunderstood my suggestion.
1. Propogation delays aren't a factor for new records, only if
you're changing a currently existing record, or the querying
server has cached the NXDOMAIN.
2. YOU can add a subdomain of one of YOUR domains, and point the MX
to the target.
3. If their box accepts based on MX, it should be ready to test seconds
after you've pointed the test domain to them.
