Layout of posts sent through email

Hello,

I want to post to my blog using e-mail.
However pictures are not sent through and the layout is like a plain text e-mail, for example:

This is a multi-part message in MIME format.

This goes on for a while as these characters represent the picture sent as attachment.
I’ve used this with a webmail client, Thunderbird and Mail.app all resulting in the same mess. I’ve tried HTML, Rich Text Format and plain text.
How do I fix this? Thanks!
