Difficulty asking questions

sending this to both of your addresses, and -questions.  You should get
three.  If you reply, esp from your apana address, I could check a) that
you can post to me at least :) and b) see what the headers suggest about
reverse IP resolution.

Seems the problem is indeed (at least temporarily) APANA's reverse DNS:

gaia: {301} dig -x

; <<>> DiG 2.2 <<>> -x
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 6
;; flags: qr rd ra; Ques: 1, Ans: 0, Auth: 0, Addit: 0
;;, type = ANY, class = IN

;; Total query time: 73580 msec
which most likely explains why freebsd.org's mx is ignoring your mail.

Probably worth mailing Matt Geier as suggested, and your local Brisbane
apana tech bods; I expect they'll want to know ..

Oh, it's worse than that .. ns.apana.org.au seems currently broken:

smithi on paqi% dig @ns.apana.org.au. -x
;; res_nsend to server ns.apana.org.au. Operation timed

smithi on paqi% dig @ns.apana.org.au. apana.org.au
;; res_nsend to server ns.apana.org.au. Operation timed

Trying another apana.org.au listed ns:

gaia: {304} dig @warrane.connect.com.au. -x
;;, type = ANY, class = IN

;; ANSWERS:       43200   RP support.brisbane.apana.org.au.       43200   TXT     "APANA Brisbane"       43200   PTR     gargoyle.apana.org.au.

126.3.203.in-addr.arpa. 43200   NS      yarrina.connect.com.au.
126.3.203.in-addr.arpa. 43200   NS      ns.apana.org.au.

yarrina.connect.com.au. 3600    A
ns.apana.org.au.        3600    A

.. but ns.apana.org.au fails to provide that PTR response right now ..
unless apana has _my_ server blacklisted of course :)

I'd be mailing that RP too (guess it's support at brisbane.apana.org.au)

Cheers, Ian
