Rmail Digest Rmail Rmail Rot13
The command M-x unrmail converts a file in Rmail format to inbox format (also known as the system mailbox format), so that you can use it with other mail-editing tools. You must specify two arguments, the name of the Rmail file and the name to use for the converted file. M-x unrmail does not alter the Rmail file itself.
