       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.  It can also act
       as  a POP3 client (if this functionality has not been disabled at build
       configuration time).


       Since masqmail is intended  to  replace  sendmail,  it  uses  the  same
       command  line options, but not all are implemented.  There are also two
       additional options, which are unique to masqmail  (-qo  connection  and

       --       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.

       -bd     Run as daemon, accepting connections, usually on port 25 if not
              configured  differently.   This  is  usually used in the startup
              script at system boot and  together  with  the  -q  option  (see

       -bi     Old sendmail rebuilds its alias database when invoked with this
              option.  Masqmail ignores it.  Masqmail reads directly from  the
              file given with `alias_file' in the config file.

       -bp      Show  the  messages  in the queue. Same as calling masqmail as

       -bs     Accept SMTP commands from stdin.  Some mailers (e.g. pine)  use
              this  option  as  an  interface.   It  can  also be used to call
              masqmail from inetd.

       -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).

       -bV     Show version information.

       -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.

       -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.

       -g [name]

              Get  mail  (using  pop3 or apop), using the configurations given
              with in the main configuration.  Without name, all  get
              configurations will be used.  See also masqmail.get(5)

       -go [interval] [name]

              Can  be  followed by a connection name.  Use this option in your
              script which starts as soon as a link to the internet  has  been
              set  up  (usually  ip-up).   When  masqmail  is called with this
              option, the specified get configuration(s) is(are) read and mail
              will  be  retrieved  from  servers on the internet.  The name is
              defined in the configuration (see

              If called with an interval option (recognized by a digit as  the
              first  characater), masqmail starts as a daemon and tries to get
              mail in these intervals.  It checks for the online status first.
              Example:  `masqmail  -go  5m'  will  retrieve  mail  every  five

              If called without name, the online status is determined with the
              configured method (see online_detect in masqmail.conf(5)).

       -i      Same as -oi, see below.

       -Mrm list

              Remove   given  messages  from  the  queue.   Only  allowed  for
              privileged users.  The identifiers of messages are listed in the
              output of masqmail -bp (mailq).

       -oem     If  the  -oi ist not also given, always return with a non zero
              return code.  Maybe someone tells me what this is good for...

       -odb    Deliver in background.  Masqmail always does this, which  makes
              this option pretty much useless.

       -odq     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 effect by setting the do_queue
              option in /etc/masqmail/masqmail.conf.

       -oi     A dot as a single character in a line does  not  terminate  the

       -q [interval]

              If  not given with an argument, run a queue process, i.e. try to
              deliver all messages in the queue.  Masqmail sends only to those
              addresses  that  are  on  the  local  net, not to those that are
              outside.  Use -qo for those.

              If you have configured inetd to start masqmail, you can use this
              option  in a cron job which starts in regular time intervals, to
              mimic the same effect as starting masqmail with -bd -q30m.

              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.  Masqmail starts as a daemon and a queue runner
              process  will  be  started  automatically  once  in  this   time
              interval.  This is usually used together with -bd (see above).

       -qo [name]

              Can  be  followed by a connection name.  Use this option in your
              script which starts as soon as a link to the internet  has  been
              set  up  (usually  ip-up).   When  masqmail  is called with this
              option, the specified route configuration is read and the queued
              mail  with  destinations on the internet will be sent.  The name
              is defined in the configuration (see

              If called without name the online status is determined with  the
              configured method (see online_detect in masqmail.conf(5))

       -t       Read  recipients from headers.  Delete `Bcc:' headers.  (Since
              0.2.25, masqmail deletes Bcc: headers in  all  cases.)   If  any
              arguments   are   given,  these  are  interpreted  as  recipient
              addresses and the message will not be sent  to  these,  although
              they might appear in To:, Cc:, or Bcc: headers.  I.e. the set of
              argument recipients is ``substracted'' from the  set  of  header

              This  behavior  is  similar  to exim's and smail's.  Postfix, in
              contrast, adds the arguments to the set  of  header  recipients.
              Sendmail  seems to behave differently, depending on the version.
              See exim(8) for further information.

       -v      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


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

       /var/spool/masqmail/  is  the spool directory where masqmail stores its
       spooled messages and the uniq pop ids.

       /var/spool/mail/ is the directory where locally delivered mail will  be
       put, if not configured differently in masqmail.conf.

       /var/log/masqmail/  is  the  directory  where  masqmail  stores its log
       mesages.  This can also be somewhere else if configured differently  by
       your sysadmin or the package mantainer.
