Hit send too soon... the other thing I wanted to bring up is it's not
uncommon to see this sort of URL encoded in hex after the part they want
you to see. This one was confusing enough, but you'll often also see
something like:

http://www.citibank.com%2e%61%33%6b%73%64%2e%50%69%53%65%4d%2e%4e%65%54

which unencoded becomes http://www.citibank.com.a3ksd.PiSeM.NeT

Just as in the url in your email, most people will see everything up to
the first "unusual" character, and won't bother to look any further.

By the way, this method of trying to steal personal info by trying to
appear as coming from a legitimate company is called phishing.
