Some people use big ugly fonts with ugly colors in their mail. However, since these people are colleagues, I'd still like to read their mail, but without hurting my eyes :)
I'd also like to keep html formatting on by default. That's why I believe there should be something like "display this sender's emails as plain text".
I've asked on superuser ( http://superuser.com/questions/43178/in-thunderbird-is-it-possible-to-block-message-formatting-for-some-senders ) before submitting here. Since several people have shown interest in this feature, I believe it would be something worth implementing, at least as an extension.
