sendmail — a mail enqueuer for smtpd(8)
sendmail [-tv] [-f from] [-F name] to ...
The sendmail utility is a mailwrapper(8) compatible interface which acts as a local enqueuer for the smtpd(8) daemon. 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: -t Read the message's To:, Cc:, and Bcc: fields for recipients. The Bcc: field will be deleted before sending. -v Enable verbose output. -f Set the sender's address. -F Set the sender's full name. To maintain compatibility with Sendmail, Inc.'s implementation of sendmail, various other flags are accepted, but these have no effect.
The sendmail utility exits 0 on success, and >0 if an error occurs.
