Just to chime in real quick, I have been aware of the problem and it's
"solution" for a while now.  There are some drawbacks to just re-writing
the headers and as the list software currently in use by the TDE project
has issues with properly rewriting the headers I've just been leaving the
list alone at the moment.  At some point this will need to change, but I
wanted to let some time elapse first in the hopes that the list software
would be updated to "natively" support DKIM.
