I tried that too; there were other RFC 2047 related header bugs but could not find this one. And the other bugs were old and fixed. Judging by the User-Agent header this is fairly up-to-date Thunderbird. It seems to be list mail. It would not surprise me that some ill-advised mailing list manager would decode and re-encode the subject. One could try sending the same message directly and through the list, and see if there's a difference. > I didn't think it was a bug, since Gmail rendered it just fine. It's possible they interpret the RFC in a more relaxed way. AFAICS notmuch relies on gmime to handle this, so I think we would have to go out of our way to work around this in notmuch. A quick search did not bring up anything gmime related about this, so I don't know if this has been discussed in the gime context. BR, Jani.
