dbmail-lmtpd - receive messages from an MTA supporting the Lightweight Mail Transport Protocol, as specified in RFC 2033.

dbmail-lmtpd [-f configfile] [-p pidfile] [-nvVh]

Mail Transfer Agents, MTA’s such as Postfix and Exim, speak LMTP to their Mail Delivery Agents which receive and store messages. DBMail implements such a system using a database backend.

-p pidfile

Specify an alternate pid file. By default the daemons use dbmail-<daemon>.pid for their pid files, saving them in the directory specified by the pid_directory entry in dbmail.conf or if that does not exist the value set by the configuration option --localstatedir, and will halt if the pid file cannot be written. Use the -p pidfile option to place the pid file in your system’s preferred location.


No daemonize: inetd mode. The program remains attached to the console from which it was started and will read and write on stdin/stdout. This is quite useful for debugging when combined with the -v option. It is also used for running from (x)inetd.


No daemonize: init mode. The program remains attached to the console and will listen on the network sockets defined in dbmail.conf. This is mostly used when running from inittab or under the control of daemontools.

-f configfile

Specify an alternate config file. The utilities are currently hardcoded to use /etc/dbmail.conf for their configs, and will halt if the config file cannot be found. Use the -f configfile option to specify your system’s preferred config file location. Debian is patched to have /etc/dbmail/dbmail.conf as the default.


Quietly skip interactive prompts and helpful status messages which would otherwise be printed to stdout. Use two -q’s to silence errors which would otherwise be printed to stderr.


Operate verbosely. Some of the utilities in the DBMail suite can take two -v’s for extra verbosity. Those which don’t understand this convention won’t complain about having the extra -v and will simply operate at their normal verbosity.
