The last time I used JavaMail I set it up differently with properties 
and MimeMessages so I didn't use quite the same method as you did to 
send.  That's one of the problems with JM, you can get at the problem 
from about 50 different ways.  If you want to write a little simple test 
program, I'll try it here.  I've got mail servers I can test it on 
although I don't have the host names with quite the same organization.

There wouldn't be MX records on the DNS for zoogz would there?
