climail

var RootCmd = &cobra.Command{
	Use:   "mail",
	Short: "The visor's mailbox, and its SMTP bridge to Postfix",
	Long: `The visor's own mailbox, and the embedded SMTP bridge for hosts
that run Postfix.

The mailbox receives mail to <anything>@<base32-pk>.skynet (or .dmsg)
on port 25 over skywire and keeps it in a Maildir. It needs no MTA,
domain or certificate: the transport authenticates every sender's PK.
It runs on every visor unless the config's "skymail" section or
"skywire cli mail settings enable=false" turns it off.

The bridge accepts SMTP from a co-located Postfix's transport_map
and dials peer visors over the visor's existing dmsg client. With
the bridge running, a Postfix transport_map line

  .skynet  relay:[127.0.0.1]:1025

routes envelopes addressed to user@<host>.<base32-pk>.skynet (or
user@<base32-pk>.skynet) over skywire to the peer's Postfix smtpd.

Without arguments, prints the state of both.

Examples:
  skywire cli mail                                  # status
  skywire cli mail inbox                            # list mail
  skywire cli mail send bob@<base32-pk>.skynet -s hi -m "hello"
  skywire cli mail up                               # bridge on
  skywire cli mail down                             # bridge off
