text: Q:
  
  receiving two emails to virtual alias
  
  have a virtual alias setup in /etc/postfix/virtual that reads:
  @mydomain.com mydomainincoming
  I then have a pipe setup in /etc/aliases that reads:
  mydomainincoming: "|/var/path_to_script/myscript.php"
  whenever I send mail to more than one user such as addy1@mydomain.com and addy2@mydomain.com, my script is called twice and is passed the exact same email both times. For 3 users, the script is called 3X. How should I set this up so that my script only receives one email even if the email is sent to more than one user?
  
  A:
  
  Have the script check the Message-ID header and only process each ID once.
