NAME         top

     sendmail — a mail enqueuer for smtpd(8)

SYNOPSIS         top

     sendmail [-tv] [-F name] [-f from] to ...

DESCRIPTION         top

     The sendmail utility is a local enqueuer for the smtpd(8) daemon,
     compatible with mailwrapper(8).  The message is read on standard
     input (stdin) until sendmail encounters an end-of-file.  The
     sendmail enqueuer is not intended to be used directly to send mail,
     but rather via a frontend known as a mail user agent.

     Unless the optional -t flag is specified, one or more recipients
     must be specified on the command line.

     The options are as follows:

     -F name
             Set the sender's full name.

     -f from
             Set the sender's address.

     -t      Read the message's To:, Cc:, and Bcc: fields for
             recipients.  The Bcc: field will be deleted before sending.

     -v      Enable verbose output.

     To maintain compatibility with Sendmail, Inc.'s implementation of
     sendmail, various other flags are accepted, but have no effect.

EXIT STATUS         top

     The sendmail utility exits 0 on success, and >0 if an error occurs.
