This always bears repeating. My brother recently had his Google mail hacked by having him click on what looked like a pretty well targeted link and it was only his bank manager's assistant noticing a strange email from him that alerted him to it.
Mind you this is one reason I don't like webmail -- having separate email and web application means you have some separation of privilege and don't have to leave a webmail account logged in and able to be scripted by a malicious link.
