NAME
     smtpd - receive incoming SMTP messages

SYNOPSIS
     /usr/lib/mail/surrcmd/smtpd [-n] [-H helohost] [-h thishost]
                                 [-L loadlim] [-l maxprocs]

DESCRIPTION
     smtpd is a daemon that normally runs while in multiuser mode, waiting
     for requests from remote hosts to send mail. smtpd listens for these
     requests on any TLI-based network for which the SMTP service is
     defined to [see netdirgetbyname in netdir(3N)]. As requests are
     received, smtpd will fork off child smtpd processes to handle each
     individual SMTP transaction.

OPTIONS
     -n             Do not create smtpsched processes to process the incom-
                    ing mail. Rely on the hourly cron(1M) invocation of
                    smtpsched instead.

     -H helohost    This option can be used to specify the name to be used
                    for the host in the initial SMTP HELO message. If it is
                    not specified, the name used in the HELO message
                    defaults to the system node name.

     -h thishost    Specifies the network name to be prepended to the
                    sender path in the From line of the message.

     -L loadlim     Specifies the maximum load at which smtpd will create
                    children. If this option is not specified, there is no
                    limit to the load at which children may run. The load
                    is determined by reading the kernel variable avenrun.

     -l maxprocs    This option is used to specify the maximum number of
                    children of smtpd that can be running at once. Each
                    child handles one SMTP conversation. If this option is
                    not specified, there is no limit to the number of chil-
                    dren that may run.

     Mail that is successfully received is put in the appropriate subdirec-
     tory under /var/spool/smtpq and smtpsched is started, if the -n option
     is not given. A log of all smtpd's activities is kept in the file
     /var/spool/smtpq/LOG.
