Yes.  Actually my /usr/src/UPDATING doesn't mention sendmail or bind being
changed between 4_3 and 4_4.  I've read the RELEASE_NOTES, README,
KNOWNBUGS, FREEBSD-upgrade for sendmail. <time elapses>  Okay, I think I
got it down now.  Logging my name server queries I get:

From the 4.3 Freebsd machine

Aack. It is trying to use inet6 and not dropping to inet4 like the 4.3
box does.  Yet if I dig with the full name it gives me a valid response
but with only "pochta" it gives me the SERVFAIL or SERVERR.  I am
rebuilding sendmail with the brokenAAAA code to see if that helps. Unless
I should be able to dig with the short hostname and have it give a valid
response (dig pochta aaaa).  I guess I'll start combing the bind website
and seeing what else I should be doing.

Thank you
