• On a Macintosh or Windows using Netscape, go to the Edit menu and pick Preferences. Then choose the Mail & Newsgroups category, and the Mail Servers sub-category. Double-click on the Incoming Mail Server (it should say pop.sas.upenn.edu). Click on the tab that says POP, and uncheck the box that says "Leave messages on server." Click OK, then click OK in the Preferences window.

Once you've taken the appropriate steps shown above, Netscape and Eudora should no longer leave copies of all of your email on the server. However, you will still need to remove the messages already stored in the inbox. First, check your email again using Netscape or Eudora to get any fresh messages. Then delete messages in your inbox in elm or Webmail.

To delete messages in webmail:
(You can only do this for one page of messages at a time.)

1. Go to https://webmail.sas.upenn.edu.
2. Log in.
3. Select the messages you want to delete by clicking the box to the left of each message.
4. Click delete.
5. Click purge.
6. When you are finished deleting and expunging all the messages you need to, click on Logout.
