title: PHP mail function requirements
body: <p>I am reading this from the PHP documentation:</p>
  
  <p>Requirements
  For the Mail functions to be available, PHP must have access to the sendmail binary on your system during compile time. If you use another mail program, such as qmail or postfix, be sure to use the appropriate sendmail wrappers that come with them. PHP will first look for sendmail in your PATH, and then in the following: /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib. It's highly recommended to have sendmail available from your PATH. Also, the user that compiled PHP must have permission to access the sendmail binary.</p>
  
  <p>My question is what is this sendmail wrapper for POSTFIX that they are talking about? Usually when I install POSTFIX with yum install the mail function just starts sending mail? Is there something more to it than that?</p>
  
  <p>Thank in advance...</p>
