advice needed, strange mail arrangement desired

[Jeff Kinz]

hi all, I need some advice

I am re-architecting my home network to use a more environmental server.
The new server uses a lot less power, has a built-in battery power
supply, and a much slower hard drive.  That's right, it's an old laptop!

this "server" will be acting as an IP tables based firewall
and an SMTP server.  I will be using a much more powerful desktop
machine as my personal workstation.

I'm trying to arrange my mail delivery system so that the server can
receive all the incoming mail but eventually deliberate to my desktop
machine, where I will be running procmail and mutt.  My MTA is sendmail
on the server, and on the desktop machine as well, since I know how to
integrate procmail and mutt with it.

Here's a simplified schematic: (needs a fixed font for proper display)


Cable Modem-->Server(laptop)-->hub-----|--->desktop
                                       |--->N other machines


so here is my question:

The desktop machine will only be running about eight hours a day, maybe
14.  So there will be periods of time when mail will becoming into the
server and its final destination, the desktop will not be available.

Can anyone give me a recommendation about how to configure sendmail on
the server so that it won't throw any of the mail that needs to get to
the desktop away, and so that as soon as the desktop comes up each
morning, or maybe after a three-day weekend, it will instantly, or
nearly instantly, or at least very soon thereafter deliver that mail to
the desktop?

Thanks in advance
