Sometimes when you try to retrieve your mail using a POP client such as Eudora or Outlook, you get an error message such as:
-ERR [IN-USE] /var/mail/.user.pop lock busy! Is another session active?
where 'user' is your user name. This happens because your mail client did not finish its work, and left the .user.pop file in the system mailbox.
This can be fixed, if you can login to the server and issue a simple command. To login to the server, you must use a secure terminal emulator client such as dataComet-Secure for Macs or SecureCRT for PC's. If you don't have one of these, they are available free from Penn ISC's Supported Computing Products page.
You also need to know your password to login. When you login, this is what you should see something like this:
