       (This list is a selection.)


       Masqmail  is  a  mail  server  designed  for  hosts  that do not have a permanent internet
       connection e.g. a home network or a single host at  home.   It  has  special  support  for
       connections to different ISPs.  It replaces sendmail or other MTAs such as qmail or exim.


       Masqmail operates in one of several exclusive modes.

       The daemon mode has two flavors that may be, and usually are, used in combination:

       Daemon (listen)
              -bd or invoked as smtpd

              Run  as  daemon.  Act as SMTP server and accept SMTP connections, on port 25 if not
              configured differently.

              This is normally used in the startup  script  at  system  boot  and  together  with
              -qINTERVAL (see below).

              Alternatively masqmail can be run with the -bs option from inetd.

       Daemon (queue)

              Run  as  daemon.   Do  regular  queue runs at the specified time interval.  This is
              normally used together with -bd (see above).

              An argument may be a time interval i.e. a numerical value followed by  one  of  the
              letters  s,m,h,d,w  which are interpreted as seconds, minutes, hours, days or weeks
              respectively.  Example: -q30m.  Combinations like -q1h30m, which sendmail  accepts,
              are not possible.

              Alternatively single queue runs (-q) can be started from cron.

       The queue processing mode has two flavors that may be used in combination:

       Single queue run (normal)
              -q (without argument) or invoked as runq

              Do  a  single queue run.  Try to deliver all messages in the queue.  Masqmail sends
              to addresses on the local host and to  remote  ones,  if  available  online  routes
              permit it.  That means, masqmail sends all queued mail it can.  Online detection is
              done with the configured method (see online_query in masqmail.conf(5)).

       Single queue run (only named route)
              -qo NAME

              Do a single queue run and deliver only using the specified online route.

              The route configuration for NAME  is  read  and  queued  mail  to  matching  remote
              recipients is sent.  (See query_routes.NAME in the main config file.)

              You  may  want  to  use  this  option  in scripts that run as soon as a link to the
              internet has been set up (e.g. ip-up).

              Obsolete behavior: Up to now: If -qo has no  argument,  the  online  connection  is
              determinded  by  online detect and, if available, mail is sent through it.  If none
              is available no mail is delivered.

              This behavior is likely to change in future versions because it is included in  -q.
              We could do something more useful instead.

       The other modes are simple ones:

       Rebuild alias database
              -bi or invoked as newaliases

              A  no-op  for  masqmail,  just exit.  Old sendmail rebuilds its alias database when
              invoked with this option.  Masqmail reads directly from its alias file (see  config
              option `alias_file'), thus no database needs to be updated.

       Accept messages
              -bm, also the default mode

              Accept  a  text message on stdin.  This is the default mode of operation.  One will
              hardly use this switch as it is the default.

              The command line options -f,-F,-i/-oi,-t are only used in this mode.

       Print queue
              -bp or invoked as mailq

              Show the messages in the queue.

       Stand-alone SMTP server

              Act as SMTP server by reading commands from stdin  and  writing  to  stdout.   Some
              mailers  (e.g.  pine) use this option as an interface.  It can also be used to call
              masqmail from inetd.

       Print version
              -bV or if called without arguments

              Print version information, then exit.

       Queue manipulation mode
              -Mrm or invoked as mailrm

              Remove given messages from the queue.  Privileged users  may  remove  any  message,
              other  users  only their own.  The message identifiers are listed when printing the
              queue (see -bp).

       The default mode:

       When no mode had been specified by either one of the above  command  line  options  or  by
       calling  masqmail under a special name, then the default mode -bm (i.e. accept messages on
       stdin) is entered.  However, if neither address arguments are specified nor -t  is  given,
       then mail can not be sent, hence something more useful is done: -bV is assumed.


       Since masqmail is intended to replace sendmail, it uses the same command line options, but
       not all are implemented.  The -qo option is additional, and unique to masqmail.


              Not a `real' option, it means that all following arguments are to be understood  as
              arguments  and  not as options even if they begin with a leading dash `-'.  Mutt is
              known to call sendmail with this option.


              ``Daemon (listen)'' mode. See above.


              ``Rebuild alias database'' mode. See above.


              ``Accept message'' mode. See above.


              ``Print queue'' mode. See above.


              ``Stand-alone SMTP server'' mode. See above.


              ``Print version'' mode. See above.

       -B arg

              arg is usually 8BITMIME.  Some mailers  use  this  to  indicate  that  the  message
              contains characters > 127.  Masqmail is 8-bit clean and ignores this, so you do not
              have to recompile elm, which is very painful ;-).  Note though that  this  violates
              some conventions: masqmail does not convert 8 bit messages to any MIME format if it
              encounters a mail server which does not advertise its 8BITMIME capability, masqmail
              does  not  advertise  this  itself.  This is the same practice as that of exim (but
              different to sendmail).

       -C filename

              Use another configuration than /etc/masqmail/masqmail.conf.  Useful  for  debugging
              purposes.  If not invoked by a privileged user, masqmail will drop all privileges.

       -d number

              Set  the  debug  level.  This takes precedence before the value of `debug_level' in
              the configuration file.  Read the warning in the description of the  latter.   Only
              root may set the debug level.

       -f [address]

              Set  the  return  path  address to address.  Only root, the user mail and anyone in
              group mail is allowed to do that.

       -F [string]

              Set the full sender name (in the From: header) to string.


              Same as -oi, see below.  Kept for compatibility.

       -Mrm msgid...

              ``Queue manipulation'' mode. See above.


              ``Me too'' This switch is ignored as, masqmail never excludes the sender  from  any
              alias expansions.

              -m is an ancient alias for -om.  Kept for compatibility.


              ``Deliver  in  Background'' Masqmail always does this.  Hence masqmail ignores this


              ``Do Queueing'' Do not attempt to deliver immediately.  Any messages will be queued
              until  the next queue running process picks them up and delivers them.  You get the
              same   (but   global)    effect    by    setting    the    do_queue    option    in


              A dot as a single character in a line does not terminate the message.

              The same as -i.


              Any other switch starting with `-o' is ignored.  This especially affects -om, -oem,


              ``Single queue run (normal)'' mode. See above.


              ``Daemon (queue)'' mode. See above.

       -qo name

              ``Single queue run (only named route)'' mode. See above.


              Read recipients from mail headers and add them to the ones specified on the command
              line.  (Only To:, Cc:, and Bcc: headers are regarded.)

              WARNING: The behavior changed with version 0.3.1!

              In  earlier  versions  command  line  argument  addresses were ``substracted'' from
              header addresses.

              The old behavior was similar  to  exim's  and  smail's  (which  are  anchesters  of
              masqmail).   The  new  behavior  is similar to the one of current postfix versions,
              which add the arguments to the set of header recipients.  (Earlier  postfix  failed
              in  case  of  address  arguments  with  -t.)  Sendmail seems to behave differently,
              depending on the version.  See exim(8) for further information.

              For masqmail the most simple approach had been taken.

              As the behavior of -t together with command line address  arguments  differs  among
              MTAs, one better not steps into this corner case.


              ``Verbose''  Log also to stdout.  Currently, some log messages are marked as `write
              to  stdout'  and  additionally,  all  messages  with   priority   `LOG_ALERT'   and
              `LOG_WARNING'  will be written to stdout if this option is given. It is disabled in
              daemon mode.


       For security reasons, before any pipe command from an alias expansion or an mda is called,
       the environment variables will be completely discarded and newly set up. These are:

       SENDER, RETURN_PATH – the return path.

       SENDER_DOMAIN – the domain part of the return path.

       SENDER_LOCAL – the local part of the return path.

       RECEIVED_HOST – the host the message was received from (unless local).

       LOCAL_PART, USER, LOGNAME – the local part of the (original) recipient.

       MESSAGE_ID – the unique message id.  This is not necessarily identical with the Message ID
       as given in the Message ID: header.

       QUALIFY_DOMAIN – the domain which will be appended to unqualified addresses.


              The main configuration for masqmail.  Depending on the settings in this  file,  you
              will also have other configuration files in /etc/masqmail/.

              The spool directory where masqmail stores its queued mails.

              The  directory  where  locally  delivered  mail  will  be  put,  if  not configured
              differently in masqmail.conf.

              The directory where masqmail stores its log messages.

       Any of the paths can be configured at compile time, and (except the main config file) also
       in  the  main  config file.  The typical paths are different, depending on the Unix system
       you use.
