Subject: strange domain name in phishing email

Can you do a packet capture, and find out what the request to the server 
looks like?

Apache 2 doesn't seem to like the decimal host definition sent by most 
browsers.  Perhaps IE 7 converts the decimal IP back into octal before 
sending it to the server.
