Set up a Windows 2003 Server with the IIS SMTP Service and no Exchange and a
big enough disk to hold all the mail. Configure it to route all mail to the
Exchange server as a smarthost, and configure the . Send it a few messages
using Outlook Express or telnet to port 25 to verify that the mail gets to
your mailbox. Reconfigure your inbound mail to go to this server before you
take down Exchange and verify that it's collecting mail. Be sure to
configure the timeout period (or whatever it's called) so that it doesn't
start bouncing mail before your server is back up. When your Exchange
server is down, the host will collect mail and hold it until the timeout
period expires.

Note that this isn't strictly necessary for a couple-day outage because SMTP
hosts sending your server mail will do the same thing. But I think you're
correct to be safe because pf the outage timeframe you're talking about.
