Configurare MUTT su linux (debian/ubuntu based)

Necessario: MUTT e SSMTP

# apt-get install mutt ssmtp

Configurazione per GMAIL:

Editare il file "ssmtp.conf" in /etc/ssmtp/ssmtp.conf in questo modo:

Per GMAIL
root=miamail@gmail.com
mailhub=smtp.gmail.com:465
UseTLS=YES
hostname=nomeserver
FromLineOverride=YES

---------------------------------------------------------------------------

Per altro gestore, ad es ARUBA
#root=
mailhub=smtp.aruba.it:25
#rewriteDomain=
#hostname=
UseSTARTTLS=NO
AuthUser=utente
AuthPass=password
FromLineOverride=YES

Creare nella directory utente (in questo caso root /root) il file ".muttrc" ed inserire:

Per GMAIL con IMAP
set imap_user = "vostra_email@gmail.com"
set imap_pass = "vostra_password"
set from = "vostra_email@gmail.com"
set realname = "vostro_nome"
set sendmail = "/usr/sbin/ssmtp -fvostro_nome -au vostra_email@gmail.com -ap vostra_password"
set folder = "imaps://imap.gmail.com:993"
set spoolfile = "+INBOX"
set postponed="+[Gmail]/Drafts"
set header_cache=~/.mutt/cache/headers
set message_cachedir=~/.mutt/cache/bodies
set certificate_file=~/.mutt/certificates
set sort = 'threads'
set sort_aux = 'last-date-received'
set imap_check_subscribed
set move = no

ignore "Authentication-Results:"
ignore "DomainKey-Signature:"
ignore "DKIM-Signature:"
hdr_order Date From To Cc

---------------------------------------------------------

Per altro gestore, ad es ARUBA
# Purge deleted message without confirm.
set delete=yes

# Don't move read message to mbox and don't ask for it!
set move=no

# Set a customized "From: " header.
my_hdr From: Pippo<info@pippo.it>

# Mailbox format should be autodetected.
#set mbox_type=Maildir

# Specifies the default location of local mailboxes.
# Default is "~/Mail".
set folder=~/Maildir

# Append sent messages to "Sent", mbox or Maildir format will
# be autodetected. The "+" sign means relative to the $folder
# directory.
set record=+Sent

# Where to store postponed messages (instead of ~/postpone).
set postponed=+Postponed

# Choose which header to hide/show, and their order.
ignore *
unignore  from: date: subject: to: cc:
hdr_order from: date: subject: to: cc:

# Select the text editor.
set editor="/usr/bin/nano -r 65"

------------------------------------------

Per inviare mail da terminale:
# echo "prova invio mail" | mutt -s "soggetto messaggio" destinatario@mail.com
