I never said that "lists are supposed to strip broken DKIM 
signatures." If you understood my words this way, then I failed to 
present the problem correctly, sorry about that.

The problem is: 
The signature was not broken until FreeBSD's list manager touched the body.

PS I recommend RFC6377 for reading. I learnt much from it.

PS2 I think I'll start PGP-signing all my messages to the freebsd lists, 
so that the mailman cannot touch the MIME-encoded body.
