Neomutt - "sasl authentication failed"


Yesterday I installed the Mail-in-a-box server in a Debian9 vps. It comes with roundcube and the setup with webmail has been running well since the beginning.
I then wanted to access the server through neomutt on my home computer.
For that, I wrote the following muttrc:

Quote:
set from = "mic@homebythefire.me"
set realname = "Miguel Caldas"
set imap_user = "mic@homebythefire.me"
set imap_pass = "xxxx"
set edit_headers = yes

set smtp_url ="smtp://mic@homebythefire.me@box.homebythefire.me:587/"
set smtp_pass = "xxxx"
set ssl_starttls = yes

set spoolfile="imaps://mic@homebythefire.me:xxxx@box.homebythefire.me/"
set folder="imaps://box.homebythefire.me/"
set tmpdir = "/tmp"
set record = "Sent"
set mbox = "+mbox"
set postponed = "Drafts"

set ssl_starttls=yes
set ssl_force_tls=yes

unset imap_passive
set imap_check_subscribed
set mail_check=60
set timeout=10
set header_cache=~/.hcache

set wait_key = no
set mbox_type = Maildir
set timeout = 3
set delete
unset confirmappend
set quit

set editor='tilde'

color normal white blue
color progress blue white
color hdrdefault green white
When I opened neomutt I was indeed seeing the server's inbox. But when I tried to send a mail, after the message
Quote:
Authenticating PLAIN
get this error message:
Quote:
SASL authentication failed
.

This is the server's Postfix "main.cf" file:

I am very new to everything about mail servers, so I really have no idea how to troubleshoot this.

Any help would be greatly appreciated
