You don't want it to relay now, there is nothing to relay to.  You want 
it to spool in /var/spool/mail and hold them til the Exchange server is 
back up.  You may have to create the user mailfiles in var/spool/mail 
unless that is already done.  Maybe it will save *@yourdomain.com in one 
big /var/spool/mail/yourdomain.com like when it was relaying.
Howto queue mail for another domain:
