Not sure on this.  At least you can script pulling each message out of 
the mailboxes and stuffing it into sendmail.  You can open each mailbox 
with Mutt and forward them all (and perhaps that can be scripted too). 
Not necessarily clean but should work.

You could deliver the mail files on disk and tell them to deal with it 
(Exchange can read mbox and Maildir, can't it?) ;-)

The way it should work is your mail server (sendmail) should be set up 
to accept mail for the client and deliver it to their mail server.  It 
should not deliver into local accounts.  Then if their server goes down 
the mail sits in the queue until it expires (and bounces) or their 
server comes up.  I'm sure the sendmail book describes how to do that.

Now you know roughly how long it takes them to recover their mail server 
so you can set your delivery timeouts appropriately.
