I'll send the dll shortly, backup your original just in case. The new dll will support utf-8, utf-32, or unicode encoding and will handle splitting the to addess on either comma or semi colon and it has better log messages. If an unknown encoding is used it will use utf-8. It also supports splitting for cc and bcc but these are not used by the contact form. Those are the only changes at this time.
No it does not currently support anything but email address.
