Test your e-mail program at this point by sending a message to yourself.

If you are able to send mail successfully, stop here. Otherwise, proceed to the troubleshooting section below:


If you are not able to send messages, you many need to run OPEN to make sure your passwords are synchronized.

If you still can't send after running OPEN, then you may need to disable the Internet Email Auto-Protect feature in Symantec AV.

This step is necessary only if you cannot send mail.

Configure Symantec AntiVirus (Version 9 or 10) so that it does not attempt to scan your mail.

(Please note that our mail server scans email before sending.)

  1. Double click the gold shield in your system tray to open Symantec AntiVirus.

  1. From the menu bar of Symantec AV, select Configure | Internet E-mail Auto-Protect.
  2. Uncheck the box for Enable Internet E-mail Auto-Protect.

  3. Click OK to Accept your changes.
  4. Click Exit to close Symantec AV.
