Mutt is a text-based IMAP client that is popular on Linux computers, and can be installed on for instance Ubuntu Linux.

To set up Mutt with Runbox, add the following to a file named .muttrc in your home directory:

set imap_user = "username"
set imap_pass = "password"

set smtp_url = "smtp://"
set smtp_pass = "password"
set ssl_starttls = yes

set from = ""
set realname = "Your Name"

set folder = "imaps://"
set spoolfile = "+INBOX"
set postponed="+Drafts"

set header_cache=~/.mutt/cache/headers
set message_cachedir=~/.mutt/cache/bodies
set certificate_file=~/.mutt/certificates

set move = no

You can now run Mutt by entering mutt at the command prompt. Then type ? for help, and q to quit.

Note: If you are using your own domain with Runbox, your smtp_url must be entered as follows:


Mutt will translate %25 to %, which is the character Runbox uses to separate localparts from domain names.
