If you are replying to a mail message (you have chosen
Message > Reply
in the mail reader) then the mailer window automatically fills in the
Message > Insert Original
to insert the text of the message you are replying to. Each line of the original message is prepended with a "
" quote prefix.
If you wish to use a quote prefix other than "
", set the value of the variable
If you are forwarding a mail message, the text of the original message is automatically included when the mailer window is created, but no quote prefix is used.
