   Jeff Liebermann's answer is interesting, but great. It's how to find   
   all the IP blocks T-mobile owns, but not how to find out which ones   
   they'll assign to customers. (And they are very unlikely to assign   
   customers IPs from the same range as say, their web site or their   
   corporate offices.)

   I did mention that. "I want to have an IP range or an include". (The   
   include gives the range(s), if you read it.) I just don't know if they   
   publish one for this use case.

   I'm aware of the meaning of -all and have been around long enough to   
   know the many diverse ways of implementing mailing lists. The   
   distinguishing factor to identify lists like that is "Do you get the   
   bounce messages when someone's email address goes bad?"
