6 Reading Your Mail

The MH-E entry point for reading mail is M-x mh-rmail. This command incorporates your mail and creates a buffer called ‘+inbox’ in MH-Folder mode. The command M-x mh-rmail shows you only new mail, not mail you have already read¹³.

There are some commands that need to read mail, such as mouse-2 over the ‘Mail’ button that display-time adds to the mode line. You can configure Emacs to have these commands use MH-E by setting the option read-mail-command to ‘mh-rmail’.

The ‘+inbox’ buffer contains scan lines, which are one-line summaries of each incorporated message. You can perform most MH commands on these messages via one- or two-letter commands in either the MH-Folder or MH-Show buffers or by using the ‘Message’ menu. See scan(1) for a description of the contents of the scan lines, and see the Figure in Reading Mail Tour, for an example.
