sendmail

sendmail emulator interface for nullmailer

sendmail [ flags ] [ recipients ] < message

This program is a front end program for nullmailer-inject. It is used by programs that expect a sendmail interface for sending email. After parsing the command-line arguments, this program executes nullmailer-inject directly, unless the -bs option is specified in which case this program executes nullmailer-smtpd to inject the mail. See the documentation for nullmailer-inject for details on how messages are reformatted and queued.
