The problem for "Relay Denied" is that the email administrator has NOT added your IP address to SMTP which will allow you to send email. If you have a connection, send the message from a Yahoo or Hotmail account if you can't send via their email system.
Send them an email which states in the subject line: "Add IP to SMTP 64.xxx.xxx.xxx" (using your correct IP address) leave the body blank. Good luck getting them to answer. I have found out the way that they assign themselves email address however: it's the person's first name@cyberonic.com. So if you were talking to Tony it's tony@cyberonic.com I have talked to others named Sam, Ken, Nick, and Mo (it's probably Mohammed). State your problem succinctly in the subject line and hope that they answer, and also send a "cc" to support@cyberonic.com.
The web mail works but is really slow, so you might try the web mail and see if you can send from there (just for the hell of it):
