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, com‐
     patible 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.
