When I write plaintext mail, I want plaintext mail. I may have formatted things carefully.

Apple Mail now does a very stupid thing. It “inserts links” into plaintext mail, so if I write “interfluidity.com” what I get is “interfluidity.com <interfluidity.com/>” (lots of bad assumptions in that conversion!)

To stop this, as far as I can tell I have to right-click each occasion and explicitly select “Remove Link”. I can’t find a general setting to prevent the behavior.

Anyone know a way?
