Can you get any information out of the core dump?
One obvious thing to try is to upgrade to the latest release of Exim
(3.02), though I don't know of any bug like this that has been fixed.

Does this happen every time for the same message? As it seems to be
related to DNS lookups, you could in fact try with -d11 in order to get
the debugging output from the resolver.

That is slightly strange. It suggests that the lookup for the MX record
did not also include the A records in the answer, which is normally
done. When I try this from here, I don't see those (A) lookups, because
the addresses come back with the MX. However, that may not be at all
relevant to the crash.
