|
||
Various special commands starting with C-c are available in sendmail mode
|
||
to move to message header fields:
|
||
\\{mail-mode-map}
|
||
|
||
If `mail-self-blind' is non-nil, a BCC to yourself is inserted
|
||
when the message is initialized.
|
||
|
||
If `mail-default-reply-to' is non-nil, it should be an address (a string);
|
||
a Reply-to: field with that address is inserted.
|
||
|
||
If `mail-archive-file-name' is non-nil, an FCC field with that file name
|
||
is inserted.
|
||
|
||
The normal hook `mail-setup-hook' is run after the message is
|
||
initialized. It can add more default fields to the message.
|
||
|
||
The first argument, NOERASE, determines what to do when there is
|
||
an existing modified `*mail*' buffer. If NOERASE is nil, the
|
||
existing mail buffer is used, and the user is prompted whether to
|
||
keep the old contents or to erase them. If NOERASE has the value
|
||
`new', a new mail buffer will be created instead of using the old
|
||
one. Any other non-nil value means to always select the old
|
||
buffer without erasing the contents.
|
||
|
||
The second through fifth arguments,
|
||
TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
|
||
the initial contents of those header fields.
|
||
These arguments should not have final newlines.
|
||
The sixth argument REPLYBUFFER is a buffer which contains an
|
||
original message being replied to, or else an action
|
||
of the form (FUNCTION . ARGS) which says how to insert the original.
|
||
Or it can be nil, if not replying to anything.
|
||
The seventh argument ACTIONS is a list of actions to take
|
||
if/when the message is sent. Each action looks like (FUNCTION . ARGS);
|
||
when the message is sent, we apply FUNCTION to ARGS.
|
||
This is how Rmail arranges to mark messages `answered'."
