  51 .Sh DESCRIPTION
  52 .Nm
  53 is a small Mail Transport Agent (MTA), designed for home and office use.
  54 It accepts mails from locally installed Mail User Agents (MUA) and
  55 delivers the mails either locally or to a remote destination.
  56 Remote delivery includes several features like TLS/SSL support and SMTP
  57 authentication.
  58 .Pp
  59 .Nm
  60 is not intended as a replacement for real, big MTAs like
  61 .Xr sendmail 8
  62 or
  63 .Xr postfix 1 .
  64 Consequently,
  65 .Nm
  66 does not listen on port 25 for incoming connections.
  67 .Pp
  68 The options are as follows:
  69 .Bl -tag -width indent
  70 .It Fl A Ns Ar mode
  71 .Fl \&Ac

 119 .Li Cc: ,
 120 and

 122 headers.
 123 The
 124 .Li Bcc:
