NO_DNS_FOR_FROM

[Jeff A. Earickson]

<x-flowed>
I've noticed the same problem, my settings listed below.  I've done
some poking thru the SA 3.0 code to try and figure out what is going
on, but I don't really know what I'm looking at.  This smells like
a bug in SA 3.0; it worked in 2.64 for me.  I contemplated filing
a bug report for SA 3.0, but I realize that my report would be
vague enough to annoy the SpamAssassin maintainers.  Anybody have
any suggestions on how to give them more info?  A debug run of
MS/SA yields little except:

debug: dns_available set to yes in config file, skipping test
