Easier said than done.

I'm on an absurd number of mailing lists, and MOST are not entirely DKIM-safe. 
I have not seen this list or any other ASF list break DKIM but I have not 
checked rigorously. A similar example is the Postfix-Users list, which very 
occasionally does some necessary restructuring of mail, breaking signatures. I 
suspect similar corner cases exist here: e.g. mail arriving with 8-bit encoding 
may cause a re-encode.

Obviously, any list that adds tags to Subject, munges From, forces or deletes 
Reply-To, or reflows text (rare, but it happens...) will clobber DKIM. Some 
sites "oversign" headers that lists should be adding (the whole List-* zoo) 
which basically is a footbullet.
