On #mutt, andrey_utkin_ reported getting a bounce trying to reply to a linux-kernel mailing list email. When he replied, vger.kernel.org bounced it because of raw utf-8 in a header.
He posted a gist at <https://gist.github.com/andrey-utkin/b204666c34613858a34844283571ce17> I don't know how long those hang around, but the problem is in the References header: <201611170549.Q3WTfoMBþngguang...@intel.com> contains the utf-8 character "þ". Are any of you familiar with the rules for Mesage-ID and References headers? Should mutt be rfc-2047 encoding/decoding the references header? What about the domain part - should we be idn encoding that part if $idn_encode is set? -- Kevin J. McCarthy GPG Fingerprint: 8975 A9B3 3AA3 7910 385C 5308 ADEF 7684 8031 6BDA
