For our Roaming customer (customers who travel) and want to use WisperTel email via a pop client like Outlook, Outlook Express, Eudora or Netscape Mail, our system allows you to send outgoing email through our mail server at mail.wispertel.net for a period of 90 minutes after you have checked your POP email.

This allows our system to "authorize" you to send email for 90 minutes from the last time you checked your pop mail. This time keeps extending if you keep checking your email.

If you get a message "relaying denied" likely you are not using WisperTel's SMTP server at mail.wispertel.net as your outbound server or you are not checking your POP email first.
