The server responded: 550 IP address nn.nn.nn.nn in XBL

For my sins my broadband is provided by AOL.  This means that I don’t have a static IP address which suits me fine.

My email is provided by Heart Internet and sometimes I get the following error message in Outlook.

Essentially this means that my PCs current IP address is on a Blocked List of IPs held by Heart Internet.  Strange that an AOL IP address would be affected in this way.

The solution.  Switch off your modem / Switch it back on and hey presto, a new (and hopefully unblocked IP address).
