Physics & Astronomy FAQ
- Email
- Why do I get the message with the following subject:
"DON'T DELETE THIS MESSAGE--FOLDER INTERNAL DATA"?
Every time you read your inbox or a Mail folder with an IMAP email client such as webmail (webmail.sas.upenn.edu) or Eudora or Netscape Messenger (set for IMAP), the IMAP server creates a file to keep track of folder data.
If you then connect to your mail.sas account with a telnet or SSH program and use elm, pine, or use a POP email client (Eudora or Netscape Messenger set for POP) to read your inbox or one of the Mail folders you read with an IMAP client, you will see these files as messages with the subject "DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA".
General rules for deleting this message are:
- If you connect to your Mail account using a telnet or SSH program and you see the message within elm, pine or alike, don't delete it. This is especially true if you use telnet or SSH and an email client (Eudora, Netscape Messenger, etc.).
- If you connect to your mail account using Eudora, Netscape Messenger, Outlook Express, Outlook, Mac Mail, or another email client with a POP configuration that downloads that message to your computer, delete the message.
