-@noindent
-The command @kbd{C-x 4 m} (@code{compose-mail-other-window}) does the
-same as @kbd{C-x m}, except it displays the mail buffer in a different
-window. The command @kbd{C-x 5 m} (@code{compose-mail-other-frame})
-creates a new frame for the mail buffer.
-
- Because the mail buffer is an ordinary Emacs buffer, you can switch
-to other buffers while in the middle of composing mail, and switch
-back later (or never). If you type @kbd{C-x m} again when you have
-been composing another message but have not sent it, Emacs asks for
-confirmation before erasing the old message. If you answer @kbd{n},
-Emacs selects the mail buffer with its old contents, so you can finish
-the old message and send it. @kbd{C-u C-x m} is another way to do
-this. Sending the message marks the mail buffer ``unmodified,'' which
-avoids the need for confirmation when @kbd{C-x m} is next used.
-
- If you want to send another message before finishing the current
-message, use the command @kbd{M-x rename-uniquely} to rename the
-current mail buffer (@pxref{Misc Buffer}). Then you can use @kbd{C-x
-m} to make a new mail buffer, and work with each mail buffer
-independently.
-
- Before using Emacs to send mail, you may need to customize the
-variable @code{send-mail-function} if your system is not set up to
-deliver mail directly via SMTP (@pxref{Mail Sending}). In addition,
-you may need to customize @code{user-mail-address} if the system
-cannot receive mail via SMTP (@pxref{Mail Headers}).
