I have a couple questions about www.smartpost.ro

1. Smartpost runs on top of mail server, and just offers the web access, not the actually email _serveing_ ? So i would need a mail server (like sendmail) before using smartpost?

2. Can a user register a new user with the web interface. I want something like yahoo, and hotmail uses to let users create email address without the need of an admin or someone else setting it up.

thanks for the help.
