[ietf-dkim] who does reputation, was detecting header mutations

Systems like Goodmail suggest that this assumuption is fundamentally 
wrong.  It puts a little flag on messages that are endorsed by a vouching 
service.  Webmail providers like it, the issues that Goodmail had with 
Yahoo et al were about the implementation, not the idea.

Speaking as a user, I have better things to do than to do the mail 
filtering that my mail system can and should be doing.  Having talked to a 
lot of people who run large mail systems at MAAWG and other places, I 
think they agree.  They use feedback from Junk buttons to tune the filters 
and manage sender reputation, not to do the primary filtering.
