Potential problems with global use of single-label names go beyond SMTP.  
For example,  RFC 4282, which defines the Network Access Identifier 
(NAI), does not permit the use of single-label names. From Section 2.1: 
 
   realm       =  1*( label "." ) label
 
As a result, someone purchasing the "example" TLD and using the NAI
bob@example in order to obtain access to the network, might well 
discover that this would not work.
