                     14: .SH DESCRIPTION
                     15: \f4smtpd\fP is a daemon that normally runs while in multi-user mode,
                     16: waiting for requests from remote hosts to send mail.
                     17: \f4smtpd\fP listens for these requests on any TLI-based network for which the
                     18: .SM SMTP
                     19: service is defined (to \f4netdir_getbyname\fP(3)).
                     20: Normally, this will only be the ``tcp'' network.
                     21: As requests are received, \f4smtpd\fP will fork off child \f4smtpd\fP
                     22: processes to handle each individual
                     23: .SM SMTP

                     29: Do not create \f4smtpsched\fP processes to process the incoming mail.
                     30: Rely on the hourly \f4cron\fP(1) invocation of \f4smtpsched\fP instead.
                     31: .TP
                     32: \f4\-H\f2 helohost\f1

                     53: The load is determined by reading the kernel variable \f4avenrun\fP.

                     56: This option is used to specify the maximum number of children of \f4smtpd\fP

                     64: Mail that is successfully received is piped to the \f4fromsmtp\fP command,
                     65: which in turn delivers the mail by piping it to \f4rmail\fP.
                     66: A log of all \f4smtpd\fP's activities is kept in the file
                     67: \f4/var/spool/smtpq/LOG\fP.
