It was saying, wrongly, that lists >are supposed to strip broken DKIM signatures. 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. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/
