I recently switched back to Mutt after 10 years of Outlook and OWA. It took a few months of constant tweaking, but loving it now. I can still load html email in a browser with one key if I need to.
i noticed the updated name when running `mutt -h` one day and was pleased to find this page
with good documentation along with an active github repository and apparently welcoming community. i think there's even a Twitter account for "keeping up with the times."
