You could also try Mail Washer (not sure of the address where you can find it, but it's sure to be found on www.download.com or you could find it in a google search). It's meant to combat spam, but it lets you preview all your messages from any pop3 or hotmail account before downloading them. It also lets you send fake bounceback messages to spammers - although I have not noticed it makes much difference. The shareware version is free and doesn't expire.
