DNS resolution worked fine in late March, but now, some resolvers (my resolver on my LAN behind NAT, and my ISP RCN's resolver) have problems with hostnames it this zone, while other (eg, Google's 8.8.8.8) do not.

These DNS queries are NOT whitewashed. You can query any hostname in the ".mail.eo.outlook.com" zone.

GOOGLE CAN RESOLVE IT . . .

$ dig anything.mail.eo.outlook.com @8.8.8.8

; <<>> DiG 9.8.3-P1 <<>> anything.mail.eo.outlook.com @8.8.8.8
;; global options: +cmd

anything.mail.eo.outlook.com. 10 IN A   213.199.154.87
anything.mail.eo.outlook.com. 10 IN A   213.199.154.23

While my resolver, and RCN's cannot:

$ dig anything.mail.eo.outlook.com @192.168.42.108

; <<>> DiG 9.8.3-P1 <<>> anything.mail.eo.outlook.com @192.168.42.108

$ dig anything.mail.eo.outlook.com @97.107.142.193

; <<>> DiG 9.8.3-P1 <<>> anything.mail.eo.outlook.com @97.107.142.193
;; global options: +cmd
;; connection timed out; no servers could be reached

The resolvers do function correctly on other zones:

$ dig +short www.google.com @192.168.42.108
74.125.131.105
74.125.131.106
74.125.131.147
74.125.131.99
74.125.131.103
74.125.131.104
$ dig +short www.amizon.com @192.168.42.108

72.21.210.29
$ dig +short www.google.com @97.107.142.193

$ dig +short www.amizon.com @97.107.142.193
rewrite.amazon.com.
207.171.166.22

IF I DIG STEP BY STEP . . .

Who is auth for outlook.com? Let's ask 192.35.51.30 (that's f.gtld-servers.net ).

$ dig ns outlook.com @192.35.51.30

Ask one of those nameservers for an answer...

$ dig soa anything.mail.eo.outlook.com @65.55.37.62

So the zone is delegated, let's lookup IP of delegated NS...

$ dig +short ns1-prodeodns.glbdns.o365filtering.com
65.55.169.42
207.46.100.42

And then ask them both...

$ dig anything.mail.eo.outlook.com @65.55.169.42

The display on these PowerEdge systems goes to sleep after some period of time. Normally, when you plug in a KVM, you have to press a key to "wake up" the display. I'm connecting these servers to a KVM switch, and I'd like the display to NOT go to sleep -- so when you select a system via the KVM switch you immediately see the console display. OS on these boxes is Linux, Ubuntu Lucid (10.04).

Nutsmail is a commercialized assembly of customized skins wrapped around the mainstream Squirrelmail software. One of the Squirrelmail plugins we're using is 'avelsieve' which provide a web interface to the server-side sieve scripts. The latest version of this plugin uses Prototype JS -- but it doesn't bring prototype with it.

I've found mention of a work around that mentions adding Prototype to squirrelmail but I'm looking for more thorough instructions. URL to the avelsieve ticket which has the mention of adding prototype manually as a work around: http://email.uoa.gr/avelsieve/ticket/267
