Virtual domain comunication

[Pierrot Driguez]

Hi folks !

For sure a silly question but...

I create a sample domain with qmail or vpopmail
(no matter) named : mydomain.fr
and a user named pierre

As created for tests, this domain name has NOT
been declared to any internet authorities.

Now, can I send a mail to a user such as :
[EMAIL PROTECTED]
from a valid provider without having a bounce ?

Seem I have a first opinion,
but any confirmation would be welcome.

Thanks
