title: php mail() prints mysterious error
body: <p>I'm trying to use the mail function in PHP, and it simply yeilds this mysterious error in the error log:</p>
  
  <pre><code>sh: 1: -t: not found
  </code></pre>
  
  <p>I have both sendmail and mailutils installed, as well as set the sendmail path in php.ini. </p>
  
  <p>I've looked at <a href="http://www.mediawiki.org/wiki/Thread:Project:Support_desk/PHP_mail()" rel="nofollow">this</a>, and I tried the suggested fixes there with no change.</p>
  
  <p>What could be causing this issue?</p>
