offline email

[Deboo <deboo@debian.elitemail.org>]

   How to send offline email? I don't think there is any option to
   store more than one email offline under mutt, pine or any other
   console mail-reader. If there is such a mail-reader, plese let me know.
   I mean how to set postfix/exim4 so that it accepts email and stores
   them and as soon as a ppp connection is detected, it connects to a
   smarthost and sends off all the email?

   Or is there a way to configure postfix/exim to just accept and queue
   the mail and sent all later when a ppp connection is made? How to go
   about it?
