It is the SpamAssassin that is calling Net::DNS which expects
file resolve.conf to reside in /etc by default.

Moreover, if your version of Net::DNS is 0.76 or later, there is
a compatibility issue with SpamAssassin. You need to upgrade the
Mail::SpamAssassin to the latest SVN trunk version, or apply
the patch, or downgrade Net::DNS to 0.75 or earlier.
