LMTPD(8) Cyrus IMAP LMTPD(8)

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 cyrus-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

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

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

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.

Run external debugger specified in debug_command.

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
