Posting by email?

Any of you folks out in the blogosphere know how to post to Blogger via email? Seeing as I'm employed now by the federal government, I can only post on my lunch hour and don't feel comfortable doing so directly into Blogger. I tried to send one post by email today, but it seems to have disappeared into the ether. If you know how to do this, please email me or post in the comments.

Muchas Gracias!
