When you are all through editing a message, you send it with the
command C-c C-c (mh-send-letter). You can
give a prefix argument (as in C-u C-c C-c) to monitor
the first stage of the delivery; this output can be found in a
buffer called ‘*MH-E Mail
Delivery*’ (see Miscellaneous).
The
hook mh-before-send-letter-hook is run at the
beginning of the command C-c C-c. For example, if you
want to check your spelling in your message before sending, add
the function ispell-message.
In case the MH
send program1
is installed under a different name, use
mh-send-prog to tell MH-E the name.
The hook mh-annotate-msg-hook is run after
annotating the message and scan line (see Sending Mail).
