title: Email relaying with php | craigslist's anonymous email generator
body: <p>I wanted to create (or at least learn/know how it is done) application(or configuration?) that does similar to what craigslist does when people choose to hide their email with the "anonymous" option when making posts. I suspect that it is done with what's called email relaying. I'd like to find out how it is done in process - from when user enter their email to receiving an email via an anonymous email address. I come from a "LAMP" background at an intermediate level so please bear with me and kindly explain.</p>
  
  <p>Your responses/comments/suggestions/pointers are greatly appreciated.</p>
  
  <p>Thank you</p>
