I just sent myself a plain text signed message from Evo and verified the
signature using TBird. Looking at the raw file, it does indeed have
a .asc attachment containing the signature, as per spec. I haven't tried
it in HTML as I never use it.

Going back to the error message in your original post, it complains
about:

gpg: BAD signature from "xxxxxxxxx (New rsa key)
<mike at my-email-server.com>"

That looks to me like a problem with the signature itself rather than
the message (though I wouldn't swear to it). Are you sure that your
configurations of Evo and TB are using the same signature?
