Sending Replies
***************

   Rmail has several commands that use Mail mode to send mail.  Only the
special commands of Rmail for entering Mail mode are documented here.
Note that the usual keys for sending mail, `C-x m' and `C-x 4 m', are
available in Rmail mode and work just as they usually do.

`m'
     Send a message (`rmail-mail').

`c'
     Continue editing already started outgoing message
     (`rmail-continue').

`r'
     Send a reply to the current Rmail message (`rmail-reply').

`f'
     Forward current message to other users (`rmail-forward').

   To reply to a the message you are reading in Rmail, type `r'
(`rmail-reply').  This displays the `*mail*' buffer in another window,
much like `C-x 4 m', but pre-initializes the `Subject', `To', `CC', and
`In-reply-to' header fields based on the message you reply to.  The
`To' field is given the sender of that message, and the `CC' gets all
the recipients of that message.  Recipients that match elements of the
list `rmail-dont-reply-to' are omitted; by default, this list contains
your own mailing address.

   Once you have initialized the `*mail*' buffer this way, sending the
mail goes as usual.  You can edit the presupplied header fields if they
are not what you want.

   One additional Mail mode command is available when you invoke mail
from Rmail: `C-c C-y' (`mail-yank-original') inserts into the outgoing
message a copy of the current Rmail message.  Normally this is the
message you are replying to, but you can also switch to the Rmail
buffer, select a different message, switch back, and yank the new
current message.  Normally the yanked message is indented four spaces
and has most header fields deleted from it; an argument to `C-c C-y'
specifies the amount to indent.  `C-u C-c C-y' neither indents the
message nor deletes any header fields.

   Another frequent reason to send mail in Rmail is to forward the
current message to other users.  `f' (`rmail-forward') makes this easy
by preinitializing the `*mail*' buffer with the current message as the
text and a subject designating a forwarded message.  All you have to do
is fill in the recipients and send.

   You can use the `m' (`rmail-mail') command to start editing an
outgoing message that is not a reply.  It leaves the header fields
empty.  Its only difference from `C-x 4 m' is that it makes the Rmail
buffer accessible for `C-c y', just as `r' does.  Thus `m' can be used
to reply to or forward a message; it can do anything `r' or `f' can do.

   The `c' (`rmail-continue') command resumes editing the `*mail*'
buffer, to finish editing an outgoing message you were already
composing, or to alter a message you have sent.
