Hi,
You don't need smtp servers on your system.
You could use any smtp server, for example
the one of your internet provider, for which
you should have a user name and a password.
You keep the details (user, password, delaytime,
etc.) regarding the mailserver in a properties
file. Open a session like this:
and start sending mails with the API's methods.
I have some additional info about sending attachments,
so if you'r interested send me a private post with
your e-mail adres.
Cheers,
Gian
