[neomutt-users] basic configuration in simple english

[jindam, vani]

hello neomutters,

i have installed neomutt. i have few 
questions. please let me know in 
simple english. my primary purpose of 
email is to send & receive emails, 
filter incoming messages into various 
group & to decide switch permanently 
to cli client. i am at present subscribed 
to half a dozen mailing lists. for 
some reason i found official guides 
too much confusing. for ex: do i 
require packages to send & receive emails?

"it" always refer to neomutt.

* does it include packages necessary 
to send & receive email?
  ** if no, where can i find guides or 
kb explain settings in great detail 
showing configuration

* encrypt all outgoing email by default.
i am unreasonable human who wants to 
encrypt all of my outgoing emails until 
'autocrypt' is adopted by top 10 webmail 
or email isps.
  ** does it handle smoothly encrypted 
emails w/o my intervention as much less 
as possible

* filtering emails
  ** does it require any extra package

regards,
jindam, vani
