Check out BSMTP:

http://exim.org/exim-html-4.50/doc/html/spec_44.html#SECT44.12
What you want to do is create a special router for outgoing mail to the
busted domain, that routes to a BSMTP appendfile transport to stick the
mail in a file. You'll probably need to do an "exim -qf" run to flush
out the deferred messages with long retry times in the queue.
Once the bad domain is fixed, remove (or disable) the router, and use
exim -bS to reinject the BSMTP file into the queue.
