That the webmail at
http://www.jetthrust.com is really worthwhile.
You can easily get your mail delivered to your IE and set up all kinds of spam filters, It even offers 15 mb of webspace AND its aviation oriented.
(This is not an advert as I even live in another continent, so I'm not gaining anything by pointing this out).
It's simly the best webmail I've come across.
