title: Catch All rule - how to catch all emails that has been sent to not existing email address
body: <p>I have a task to create a new rule that must catch all email messages  which will be send to domain with exception - this rule can not concerns existing users.</p>
  
  <p>For example:</p>
  
  <p>I have three users:</p>
  
  <p>user1@domain.com</p>
  
  <p>user2@domain.com</p>
  
  <p>catchall@domain.com</p>
  
  <p>When somebody will send any email message to user3@domain.com, user4@domain.com... all emails send to this addresses will be redirected to catchall@domain.com.</p>
  
  <p>In brief - when somebody send email on address that not exist in this domain, this message will be send to address catchall@domain.com</p>
