Well, let's see:
[root at tempest /]# nslookup blueonyx.it ; nslookup main.blueonyx.it
[root at tempest /]# nslookup 184.108.40.206
220.127.116.11.in-addr.arpa name = main.blueonyx.it.
Actually I don't see a problem there.
The listserver sends as "main.blueonyx.it.", as you can see when you look at
one of the headers of an email you get from the list. The reverse of the IP
18.104.22.168 points to "main.blueonyx.it."
So we have a couple of A records covering all our "bases", a very correct PTR
(thanks to Chris Gebhardt!) and we have three MX records:
main.blueonyx.it --MX(30)--> www.blueonyx.it
www.blueonyx.it --MX(30)--> www.blueonyx.it
blueonyx.it --MX(30)--> www.blueonyx.it
That should do it all very nicely. No idea what cripes Barracuda has with that
With best regards
