Prepare a message template.

Parameters
fpIf not NULL, file containing the template
mIf fp is NULL, the Mailbox containing the header with the template
e_newThe template is read into this Header
eEmail to recall/resend
resendSet if resending (as opposed to recalling a postponed msg) Resent messages enable header weeding, and also discard any existing Message-ID and Mail-Followup-To
