SEND-MAIL

Queued on  exit.!
 1:m(m.mSend Mail)

!Send Mail:! !C Enter recursive ^R mode editing mail, queued on ^R exit.
Given a numeric argument, continues editing previously-aborted (or sent) mail.
User is prompted initially for TO, CC, and SUBJECT fields.
Then user edits the message in a recursive ^R.  (The user in that ^R can
    change the header if desired.)
Upon ^R exit (e.g. by C-M-Z, ^Z^Z) the message is queued for mailing.
The message is edited in an EMACS buffer named *Mail*, and the text in it
    will stay around even after the mail is queued.!
