This is one of those simple-sounding questions that unfortunately does
not have a simple answer. Firstly, I presume you mean a single message
with a single undelivered recipient.
It depends on what caused the defer. If it was a DNS lookup failer -
i.e. a routing defer - then it won't do the routing, and so won't do a
DNS lookup. However, if the defer was because there was a host problem,
then it will do a DNS lookup (to find the host) and then it will notice
that that host is still deferred.
