Yep.

Of course, if you 
aren't going to break the signature, or are rewriting the From:
address, 
then it's OK to forward the email.

Probably.

if you are rewriting the from and put the original sender in the sender: field, 
most MUA will display it like this:

Sent by JD Falk
on the behalf of DKIM-WG

Seems strange to me.

If you rewrite only the From: header then the MUA will display

from: DKIM-WG

then you hope there is a signature of some sort to know who sent the email 
originally.
