NAME

       lmtpd - 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 cyrmaster(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
              Read configuration options from config-file.

       -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 dis-
              able 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.
