rails 3 email question: how to get /usr/sbin/sendmail executable file?

in rails 3 sendmail_settings, there is a option :location which represent the location of the sendmail executable (Defaults to /usr/sbin/sendmail). In my开发者_开发知识库 ubuntu OS machine, there is no such file under /usr/sbin, how can I get /usr/sbin/sendmail executable then?

If you want to override options for the :sendmail delivery method then you can use sendmail_settings. You can override these setting in your environment file.

config.action_mailer.sendmail_settings = {
  :location => '/usr/sbin/sendmail',
  :arguments => '-i -t'
}

sudo apt-get install sendmail-bin. You should have done a search using a package manager. It's ubuntu.. Also it looks like gzipped executables can be found all over the web.
