I'm not a developer and I'm still rather new to Emacs. Also, as far as I understand, notmuch uses gnus for compose mode. But I'm stuck and wondering if anyone has a solution: When sending mail from Emacs, the text does not appear to respect line breaks when read on a mobile phone. Instead, there appear to be random line breaks in the text, which makes reading emails rather frustrating. My understanding is that some time ago, an RFC was passed to make email compatible for viewing on mobile devices. This solution is format=flowed. For background, see: http://joeclark.org/ffaq.html I've been trying to implement this solution in gnus, but haven't come across a solution. Google suggests I'm not the only one experiencing this issue, see: http://stackoverflow.com/questions/41299350/how-can-i-send-messages-with-format-flowed-with-the-notmuch-message-client https://www.reddit.com/r/emacs/comments/55ydkd/gnus_and_formatflowed/ The EmacsWiki has a page on gnus and format=flowed, but I've found it pretty hard to decipher: https://www.emacswiki.org/emacs/GnusFormatFlowed. The wiki suggests that format-flowed is enabled in gnus, which doesn't seem to make sense with my experience so far. It also suggests that "if you want dynamic reflowing, simply unfold encoded lines to full length and setup article buffers to wrap." I have no idea what this means (see the reddit thread for more confusion). It also seems to suggest using use-hard-newlines, while at the same time suggesting that it makes no difference. I actually gave this a shot, and the wiki was right: it made no difference. My only remaining lead is that perhaps the issue isn't with gnus at all, but with my smtp client, msmtp. See: https://github.com/djcb/mu/issues/569. It's from the mu github, but assuming mu4e also uses gnus and/or doesn't "send the mail", then perhaps that's a potential answer. To recap: 1. If notmuch handles composition, then this is either a bug report or a feature request. 2. If notmuch does not handle composition, I'd appreciate insight from anyone who has managed to resolve this issue. 3. Or, any hints as to whether it's worth sending this email to the gnus/emacs/msmtp mailing lists. Thanks! David -- dwrz|朱为文
