SMTPD en OpenBSD

Nuevo smtpd en OpenBSD 5.7

/etc/mailer.conf

   The file /etc/mailer.conf contains a series of pairs.  The first member
   of each pair is the name of a program invoking mailwrapper(8) which is
   typically a symbolic link to /usr/sbin/sendmail.  (On a typical system,
   newaliases(8) and mailq(8) would be set up this way.)  The second member
   of each pair is the name of the program to actually execute when the
   first name is invoked.  The file may also contain comments, denoted by a
   `#' character in the first column of any line.

/etc/mail/smtpd.conf

   smtpd.conf is the configuration file for the mail daemon smtpd(8).

smtpctl

     The smtpctl program controls smtpd(8).  Commands may be abbreviated to
     the minimum unambiguous prefix; for example, sh s for show stats.

     The following commands are available:

     encrypt [string]
             Encrypt the password string to a representation suitable for user
             credentials and print it to the standard output.  If string is
             not provided, cleartext passwords are read from standard input.

             It is advised to avoid providing the password as a parameter as
             it will be visible from top(1) and ps(1) output.

     log brief
             Disable verbose debug logging.
  
     log verbose
             Enable verbose debug logging.
  
     monitor
             Display updates of some smtpd(8) internal counters in one second
             intervals.  Each line reports the increment of all counters since
             the last update, except for some counters which are always
             absolute values.  The first line reports the current value of
             each counter.  The fields are:
  
             o   Current number of active SMTP clients (absolute value).
             o   New SMTP clients.
             o   Disconnected clients.
             o   Current number of envelopes in the queue (absolute value).
             o   Newly enqueued envelopes.
             o   Dequeued envelopes.
             o   Successful deliveries.
             o   Temporary failures.
             o   Permanent failures.
             o   Message loops.
             o   Expired envelopes.
             o   Envelopes removed by the administrator.
             o   Generated bounces.
  
     pause envelope envelope-id | message-id
             Temporarily suspend scheduling for the envelope with the given
             ID, or all envelopes with the given message ID.

             ID.

             time since the last connection.

     show hoststats

             the list of connectors (source addresses to connect from for this
             relay).

     show routes
             Display status of routes currently known by smtpd(8).  Each line
             consists of a route number, a source address, a destination
             address, a set of flags, the number of connections on this route,
             the current penalty level which determines the amount of time the
             route is disabled if an error occurs, and the delay before it
             gets reactivated.  The following flags are defined:

             D   The route is currently disabled.
