title: PowerMTA: How to forward messages to external SMTP servers
body: <p>We have a PowerMTA server that receives incoming e-mail. Is it possible to forward specific domains to another existing SMTP server that's not running PowerMTA?</p>
  
  <p>The solution that I found so far is to pipe the e-mails to mailx that's pointing to another SMTP server, but this looks hack-ish.</p>
  
  <p>Thanks!</p>
