This obviously isn't a feature, but I wanted to mention that I will be moving away from Mutt maintainership after this release. There isn't a transition plan, so I'll keep maintaining the 2.2.x series with bug fixes and security issues.
It's been my pleasure to keep the releases coming since version 1.5.24. Unfortunately the past year, my time and energy available has been decreasing. So my plan is to focus the time I do have on keeping Mutt stable, secure, and bug free; until someone else has the desire to head up (and support) new-feature releases. Thank you everyone! "
Thanks Kevin !
A good alternative, if you are looking, is Notmuch. In fact, the Notmuch engine (there's also a Notmuch Emacs mode, and many other frontends) is frequently used in conjunction with Mutt and also powers NeoMutt.
The second hardest thing was actually streamlining using it with gmail accounts.
Sending would probably be easier ( use a real smtp server)…
