SMTP Authentication is NOT supported in older email software such as Microsoft Internet Mail (included with Windows 95), Eudora Lite, Eudora Pro, Eudora 4.2, Netscape Navigator, or Outlook Express 4.

Note: When upgrading your email software, most email programs will retain your current settings and messages. However, PenTeleData can NOT guarantee that your saved addresses and email messages will not be lost after upgrading. For this reason, we recommend that you backup any important messages and your address book prior to performing any upgrades.
