That's an interesting patch. >For other email lists, like this one, you need to account for the [listname] >tags. You can include the original subject on signing and do a comparison with the new subject line before using the original subject for verification. >my opinion is that gracefull handling of email lists fudges will ultimately >determine if DKIM is readily adopted in an organisation. It's one-to-one communication that's more important and that's where DKIM can make a difference. Mailing list failures aren't critical unless we do an outright reject on verification failures. You are right in that organisations may push off adoption until mailing lists are handled gracefully. >perhaps the verification process could almost brute force the email list >mangles.

Is it worth it? If we want to increase the pass rate only, it may be worth it. The last lines would have to be removed which means doing a body rewrite. That has a significant overhead. I made a suggestion above on how the subject line can be unfudged. >Am I missing something in the standard that says a verifying server >should not >attempt to verify the original signature?
