To configure neomutt for the first time is tricky, even more if you want to use multiple email accounts.
For some users it's a matter of personal choice. For othersas me, it's the only option.
Half an hour to make my two work email accounts work fine. Well, the good part of it is that as soon as you get the right config, reinstalling or installing this e-mail client on other computers is a matter of seconds.
