As somebody else mentioned today there seems to be something fishy with
the bluewin mailservers, I guess the culprit is the "Load balances"
which seem to act as NS's. But as these are really nice Load Balancers
are future proof, the real hurdle they are hitting is quite simple:
that bloody IPv6...
Lets dig the loadbalancers  for the answer:
$ dig @ns.bwlbmsg1zhh.bluewin.ch. mxbw.bluewin.ch. aaaa
; <<>> DiG 9.4.1-P1 <<>> @ns.bwlbmsg1zhh.bluewin.ch. mxbw.bluewin.ch. aaaa
; (1 server found)
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 22394
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

And tada, my sweet postfix/bind/powerdns combo will give up on it as
there is clearly no answer to be gotten for that hostlabel.
As such I would *love* to mail postmaster(a)bluewin.ch (assuming that
somebody is at home there), but without taking out AAAA requesting out
the whole chain of software I really can't mail them :(
Not falling over the folks from Bluewin, but it is the only way to
contact them AND to show how things can break in mysterious ways :(
The BBC had a similar problem a few years back. I do hope that you folks
can fix this up, I noticed this actually because a @bluewin.ch user
couldn't signup to SixXS as she was getting rejected.
Hmmmm, now that we are trying to query those boxes some more I can't get
this answer out of this setup....
Please folks @ Bluewin, check this out and fix it ;)

This is probably somewhat off-topic, but some of you guys might have a
hint for me.
I've been researching the various offers of dedicated hosting in
Switzerland, mostly looking at providers listed on providerliste.ch.
Everything I have come across is not only 4-5 times the price of what
we're renting right now (at Hetzner in Germany), it is also technically
At Hetzner, the entry level DS3000 is a dual-core 64Bit AMD, 2Gb RAM and
2x400Gb disk. Plus 1Tb transfer-volume/month. This is available at
To get anything remotely similar in Switzerland I have to pay SFr300 or
more per month. Given that we would need 4 or 5 such servers,
colocation very quickly becomes interesting instead.
Have I missed any really good dedicated server offerings? Any
colocation places in or around Zurich you would recommend?

Does anyone have handy the cisco-avpair for tuning an interface
delay via Radius? Like:
Cisco-AVPair: "lcp:interface-config=bandwidth 5632"
(but that's for.. bandwidth)

I find it verry strong that they are blocking a complete AS in the Spam list.
At the Moment is the Sunrise AS Blocked.
I hope some of the Sunrise is doing some.
