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.


Examples
========

**lmtpd** is commonly included in the SERVICES section of
cyrus.conf(5) like so:

   SERVICES {
       imap        cmd="imapd -U 30" listen="imap" prefork=0
       imaps       cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
       **lmtpunix    cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20**
       sieve       cmd="timsieved" listen="sieve" prefork=0
       notify      cmd="notifyd" listen="/var/run/cyrus/socket/notify" proto="udp" prefork=1
