I have lots of mailboxes internally that have mail shoveled to them based on From:. If the mail is from a source that I trust, "i=" would be just as useful that way. As a filtering agent at the border, or one protecting lots of sites (a cloud-based filter maybe), I could use "i=" as supplementary reputation information if it's from a domain that I generally trust. So mail from example.com, which has a good reputation or is whitelisted, can be further vetted using "i=" since I implicitly trust it's being used properly. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
