VZ and VZW are completely separate (from an SMTP point of view)

To get an answer on the VZW mail filtering issue, we'd have to talk to a
mail admin at Verizon Wireless, as described by my acquaintance at Verizon


   You can let your contact know that Verizon Wireless does have some
employees on the list and it's been taken care of. I've forwarded
Christ w/Globalstar's issues on to appropriate parties within VZW.

   As a reiteration, VZW's network infrastructure is completely
seperate from Verizon's. (with the exception of where they are a LEC)
