How Do I Move Messages from the Mail Spool?
The Mail Spool
Typically, a user will simply wish to delete old mail to free up space. However, if there is an excess of important mail which the user would like to store for future use, they must manually move it to either mbox, or to a mailbox of their choice. For more information, see the Answers article on mail cleanup.
To move mail from the spool using mutt, highlight the message to be moved in mutt's message list, and hit s. A prompt will appear at the bottom asking for a file name. To place it in the typical file for saved mail, backspace through the name it has generated, and enter ~/Mail/mbox. If you prefer, you may replace mbox with a different name. An example would be saving messages from your boss in a mailbox named ~/Mail/bossmail. Once saved, these messages are automatically marked for deletion from the inbox.
If the user wishes to view saved messages later, they may type "c" in the message list. Again prompted at the bottom for a mail box, the user should type ~/Mail/mbox or the alternate name chosen earlier.
To move mail from the spool using Pine, enter Pine's message index and highlight the message to be moved. Hit "s" and enter the path and filename of the desired mailbox (typically ~/Mail/mbox). The message will be appended to the specified file and marked for deletion from the inbox.
To view the new mailbox, type "g" and enter the path and filename of the new mailbox (i.e., ~/Mail/mbox).
To move mail from the spool using Elm, highlight the message in the list, and type "s". When prompted at the bottom of the screen, type the desired mailbox path and filename (typically ~/Mail/mbox). The message is then marked for deletion from the inbox and copied into the new mail box.
To view other mail boxes such as the newly created, type "c" in the message list and enter the path and filename of the desired mailbox (Example: ~/Mail/mbox).
