Does Exim ever change messages with respect to the MIME encoding of parts, if the MIME ACL is not used? That is, can it take an encoded message, take it apart, and re-encode it (possibly changing the message's bit representation)?
The context is the link below and down the thread from there. I have seen this problem for years and many other parts of my email setup have been changing. Exim has been the one constant, and I never allowed myself to suspect it. But after the last message from Kevin McCarthy, I do suspect it. http://lists.mutt.org/pipermail/mutt-users/Week-of-Mon-20181022/000488.html See also https://very.loosely.org/itz-blog/the-problem-with-gpg-signatures.html which describes the same problem as I tried to solve it more than a year ago, with quite a different setup (but still behind exim). -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
