title: Postfix - How to process incoming emails?
body: <p>Does anybody know how to process incoming emails for virtual mailboxes in postfix?
  I am building web application where users add new content by sending emails to application. 
  Email address used for each user is custom (eg. 123456@myservice.com) and it is dynamically created as a Postfix virtual mailbox. User needs to be able to send email to his custom mailbox address (as12145ed@myservice.com) and i want to process each incoming email, parse it's contents and populate my database with data from email.
  I tried using <a href="http://www.postfix.org/FILTER_README.html" rel="noreferrer">Postfix After Queue filter</a> but what i really wont is to process emails once they are saved in users virtual mailbox folder.</p>
