mkdir -p ~/.mutt/cache/headers
mkdir ~/.mutt/cache/bodies
touch ~/.mutt/certificates
touch ~/.mutt/muttrc

Contents of .muttrc (without my email ofcourse)
# .muttrc

set use_from = yes
set envelope_from = yes

set folder = "imaps://imap.gmail.com:993"

set move = no
set imap_keepalive = 900

set imap_user = '<user>@gmail.com'
set imap_pass = ''

set smtp_url = "smtps://<user>@gmail.com@smtp.gmail.com:465/"
set smtp_pass = ''

set ssl_starttls = yes
set ssl_force_tls = yes

set spoolfile = +INBOX
set record = "+[Gmail]/Sent Mail"
set postponed = "+[Gmail]/Drafts"
set mbox="imaps://imap.gmail.com/[Gmail]/All Mail"
set trash="imaps://imap.gmail.com/[Gmail]/Trash"

set header_cache = "~/.mutt/cache/headers"
set message_cachedir = "~/.mutt/cache/bodies"
