Синопсис (Synopsis)
smtpd [-dFhnv] [-D macro=value] [-f file] [-P system] [-T trace]
Описание (Description)
smtpd is a Simple Mail Transfer Protocol (SMTP) daemon which can be
used as a machine's primary mail system. smtpd can listen on a
network interface and handle SMTP transactions; it can also be fed
messages through the standard sendmail(8) interface. It can relay
messages through remote mail transfer agents or store them locally
using either the mbox or maildir format. This implementation
supports SMTP as defined by RFC 5321 as well as several extensions.
A running smtpd can be controlled through smtpctl(8).
The options are as follows:
-D macro=value
Define macro to be set to value on the command line.
Overrides the definition of macro in the configuration
file.
-d Do not daemonize. If this option is specified, smtpd will
run in the foreground and log to stderr.
-F Do not daemonize. If this option is specified, smtpd will
run in the foreground and log to syslogd(8).
-f file
Specify an alternative configuration file.
-h Display version and usage.
-n Configtest mode. Only check the configuration file for
validity.
-P system
Pause a specific subsystem at startup. Normal operation
can be resumed using smtpctl(8). This option can be used
multiple times. The accepted values are:
mda Do not schedule local deliveries.
mta Do not schedule remote transfers.
smtp Do not listen on SMTP sockets.
-T trace
Enables real-time tracing at startup. Normal operation can
be resumed using smtpctl(8). This option can be used
multiple times. The accepted values are:
• imsg
• io
• smtp (incoming sessions)
• filters
• transfer (outgoing sessions)
• bounce
• scheduler
• expand (aliases/virtual/forward expansion)
• lookup (user/credentials lookups)
• stat
• rules (matched by incoming sessions)
• mproc
• all
-v Produce more verbose output.
