title: Can a SaltStack sls file use postfix set_main to set a variable in main.cf?
body: <p>Can I set <code>relayhost = [1.2.3.4]</code> in /etc/postfix/main.cf via a salt sls file equivalent to the salt command below?</p>
  
  <blockquote>
    <p>salt 'mymachine.*' postfix.set_main relayhost "[1.2.3.4]"</p>
  </blockquote>
  
  <p>If so what would the sls file contents be?</p>
