That's not so clear. RFC2822 is explicitely not about disk storage; see the Scope paragraph of RFC2822 or RFC522. I think most peoples unix mail delivery agents use line feeds, otherwise more people would be having problems resending mail. See e.g. point 2 in https://www.exim.org/exim-html-current/doc/html/spec_html/ch-message_processing.html Be that as it may, apparently your system is using CRLF. > > According to this [2] Emacs normally converts line endings to only 'nl' > (newline) when opening a DOS file.

Yes, notmuch-show-resend-message uses notmuch-show-view-raw-message, which intentionally turns off any conversion > > David, I assume your system is also a Linux, does > > notmuch show --format=raw id:1472041345236.7...@de.bosch.com | od -a > > also show 'cr' and 'nl' as line ending? No, I don't have carriage returns in my actual files on disk, and consequently not in the output of notmuch show --format=raw. I suspect notmuch is mostly fine with CRLF line endings, due to mainly passing everything through gmime. But in the case of notmuch show --format=raw, this is not the case. I did confirm that adding CRLF line endings to an existing mail file causes the symptoms you originally described. I'm still not sure the best place to fix this; I'm pretty sure upstream emacs won't accept your change (or equivalent) to mime-to-mml. d _______________________________________________ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
