I'm not sure I understand. You can send emails using Roundcube webmail? Or, webmail allows you to send, but the emails are not being sent out of the server? Are you using a webmail relay? Almost all VPS and personal servers require that you use a mail relay to send out your emails such as gmail or your own ISP.
Me.B is a bit better at email than I currently am. Still learning the *nix style (Transferred my server a while back from Windows.)
