I am very naive/ 'ignorant'/ of mail server behavior, so I hesitate to 
enter this thread, but I think I am understanding that Jo-Anne 'should' 
use a Sender field in such as Tb.

But, as I read about native 'features' and add-ons for Tb, I see that it 
isn't very hard to gain a Sender field for received mail, but creating a 
Sender field for outgoing mail is not so easy.

Am I correct in my understanding?
