CVS shows:

* smtpserver/mxverify.c:
    When doing varioud "RBL" lookups, always catenate a "."
    into end of the lookup domain in order to suppress
    unnecessary "search" work by the resolver libraries.
    Doing:  _res.options &= ~RES_DNSRCH;  might do it too...

http://www.zmailer.org/cgi-bin/cvsweb.cgi/zmailer/smtpserver/mxverify.c.diff?r1=1.27&r2=1.28&f=h

Reading that shows what the original error was...
I applied Eugene's patch manually.
