NAME         top

       sendmail — a mail enqueuer for smtpd(8)

SYNOPSIS         top

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

DESCRIPTION         top

       The utility is a local enqueuer for the smtpd(8) daemon,
       compatible with mailwrapper(8).  The message is read on standard
       input (stdin) until encounters an end-of-file.  The 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
       , various other flags are accepted, but have no effect.

EXIT STATUS         top

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