Hmmm, this is interesting I didn't think AIX on the RT or RS6000 even had
the res_search() code. res_search() was introduced in BIND 4.8 if memory
serves and the code on the RT or 6000 as shipped is much earlier than
that. And, by the way, the simplest way to get the information you want
is to get the BIND distribution, its available from Berkeley or most any
other of the Internet archive sites. AIX 1.2 on the PS/2 or 370 has this
code since I ported it, but since it was done in the service stream it is
not in the documentation. This will be remedied in the AIX 1.2.1 docs. Is
it possible that someone has hacked your system and added the later version
of BIND (and from the sound of it got it wrong :-})?? You might try running
sendmail with debug on and take a look at the info from the nameserver (that
assumes of course that your resolver was built with DEBUG defined).

Disclaimer: I don't speak for the company.
