title: Postfix/Amavis: local account outgoing mail filter ignored, virtual outgoing filtered
body: <p>I have a postfix mail server which sends email from both virtual addresses and from local Unix accounts, through a PHP script using mail().</p>
  
  <p>I've installed Amavis and have successfully configured filtering and and the addition of mail signatures for the virtual addresses, but the signatures are not added for any mail sent by the local accounts (e.g. through a script or the mail command)</p>
  
  <p>I've tried a heap of config and routing changes but no luck- does anyone please know how to filter such local outgoing mail? </p>
  
  <p>Thanks! </p>
