How does someone with a www.blogger.com site blog remotely by e-mail? - e blogger glory hole

I have a blog at www.blogger.com and was told that I can send blog entries via e-mail. Firewall will not let me have www.blogger.com. How do I add my blog posts on my lunch hour and e-mail as soon as I on the site?
