sendmail(8)
NAME
sendmail --- a mail enqueuer for smtpd(8)
SYNOPSIS
sendmail [-tv] [-f from] [-F name] to ...
DESCRIPTION
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.
EXIT STATUS
The sendmail utility exits 0 on success, and >0 if an error occurs.
