It seamed ORDB (ORDB.org was shut down on December 18, 2006) changed since yesterday their behaviour, and instead of timing out, they are blocking all IP addresses (every e-mail server queried is being reported as an open relay). If your mail infrastructure uses ORDB, the sender will get a message like this one (this is an example blacklisting the Gmail servers): 

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 13): 550-Message rejected because ag-out-0708.google.com [72.14.246.240]:20081 is
550-blacklisted at relays.ordb.org see ordb.org was shut down on December 18,
550 2006. Please remove from your mailserver.

The reason behind this active behaviour change is not clear yet, if we get more information we will update this entry here.

Telnet is now made an optional component in Vista (and Longhorn Servers). This means if you type telnet in command shell, you will be out of luck.

To get this usefull tool back, you can use the software explorer or Click Start, ControlPanel, Programs, and then Turn Windows Features on or off. In the list, scroll down and select Telnet Client. Click OK to start the installation.

As time has passed, fewer users use telnet. Thus, to decrease the foot print as well as the attack surface, we decided to make it an optional component.
