Instalas mutt:
apt-get install mutt
Configuras mutt (usualmente, .muttrc en tu home):
set from = "user@gmail.com"
set realname = "Guillermo Garron"
set imap_user = "user@gmail.com"
set imap_pass = "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 smtp_url = "smtp://user@smtp.gmail.com:587/"
set smtp_pass = "password"
set move = no
set imap_keepalive = 900
(nota: imap_user e imap_pass no son necesarios para envío).
Envías correo:
mutt -s "Subject" [direccion] {direccion 2} {...} {-a "Adjunto"}
o bueno, con la redirección del cuerpo.
