NAME

       lmtpd - Cyrus IMAP documentation

       LMTP server process

SYNOPSIS

       lmtpd [ -C config-file ]  [ -U uses ] [ -T timeout ] [ -D ] [ -a ]

DESCRIPTION

       lmtpd  is  an LMTP server used to deliver mail to the IMAP mailstore.  It accepts commands
       on its standard input and responds on its standard output. It MUST be invoked by master(8)
       with those descriptors attached to a remote client connection.

       lmtpd  reads  its  configuration  options  out  of the imapd.conf(5) file unless specified
       otherwise by -C.

OPTIONS

       -C config-file
              Use  the  specified  configuration  file  config-file  rather  than   the   default
              imapd.conf(5).

       -U uses
              The  maximum  number  of  times that the process should be used for new connections
              before shutting down.  The default is 250.

       -T timeout
              The number of seconds that the process  will  wait  for  a  new  connection  before
              shutting  down.   Note  that  a  value  of  0 (zero) will disable the timeout.  The
              default is 60.

       -D     Run external debugger specified in debug_command.

       -a     Preauthorize connections initiated on an internet socket, instead of requiring LMTP
              AUTH.  This should only be used for connections coming from trusted hosts.
