Quoting RFC 822:

Note:  THE USE OF DOMAIN-LITERALS IS STRONGLY DISCOURAGED.  It
       is  permitted  only  as  a means of bypassing temporary
       system limitations, such as name tables which  are  not
       complete.

I want to test an app by writing a quick/dirty wrapper that sends mail to a 
single, known, mail server and avoids DNS lookup.
