title: IMAP forwarder
body: <p>I'm wondering what is the quickest and most reliable way to forward mail from an IMAP account.</p>
  
  <p>My university does not allow our student-mailbox to forward to a private e-mail account (everybody uses either Gmail or Hotmail here). It's a political thing, not technical. We do have IMAP access to the mailbox. I would like to have a service which downloads the mail through IMAP, and forwards. And it would be nice to scale it, so thousands of students can use it. Eventually, I want to build a public signup page, and have it processed automatically from there. </p>
  
  <p>So far, I've made a decent PHP script which connects, downloads headers and body parts, and ties it all together. I have two problems with that. </p>
  
  <p>1) I'm downloading all kind of parts, and sticking them back together. I hope that every exotic attached file, weird encoded piece of text and every type of header survives this. I'm not even sure I have the complete header.</p>
  
  <p>2) The to: e-mail address becomes the private e-mail address, not the original student e-mail address. I think this is lame, and inconvenient in searching and archiving.</p>
  
  <p>Is the PHP script the way to go? Is there a trick using a particular linux mail service/daemon? Does IMAP have a 'forward' command, I'm missing? </p>
