Mutt is configuration-driven, and has no formal setup process. For this reason, we have included an example Mutt configuration file to get you started connecting your Lavabit email account.
# Example Lavabit Mutt config file.
set folder = imaps://imap.lavabit.com:993 # Choose either POP or IMAP.
set imap_user = example # The first part of your Lavabit email address. (i.e. "example" in "example@lavabit.com")
set spoolfile = +INBOX
set postponed = +Drafts
set record = +Sent
mailboxes = +INBOX
set smtp_url = smtp://smtp.lavabit.com:587
