Most likely it's just taking a long time to look up the relevant DNS records -
an "MX" lookup for the domain in question, then an "A" (or maybe "ANY") lookup
for each MX thus found.

I just tried this with the "mx" command (from the Ubuntu "host" package), and
the lookups are very slow. This would make exim appear to hang.
