title: postfix; pipe mail content to script for all mail of specific subdomain
body: <p>i'm trying to get postfix to accept the vacation.pl script, as supplied by the vacation plugin for roundcube (i'm interested in calling scripts when receiving mail for specific domains / subdomains). So far everything seems to work out.. except the script is not called ;)</p>

  # now what should fire the "vacation" script is the fact that there is an mysql table entry in:
  mysql&gt; select address,goto from alias where address='peter@example.com' and active=1;
  +-------------------------+-----------------------------------------------------------------------------------------------+
  | address                 | goto                                                                                          |

  | peter@example.com | peter@example.com@vacation.example.com,peter@example.com,peter@foobar.org |
  </code></pre>
  
  <p>so in theory whatever i send to peter@example.com gets saved into peter@example.com's mailbox, then gets forwarded to peter@example.com@vacation.example.com and to peter@example.com@vacation.example.com. the second very strange email address in the database that is not really correct was not my idea but is the result of enabling vacation via the roundcubemail vacation.pl plugin.</p>
  
  <p>so the problem is when i send mail to peter@example.com, the forward to peter@foobar.org works, but something in the forward to strange peter@example.com@vacation.example.com doesnt work as the script is never called that should be called with the mail piped into it when receiving mail for .vacation.example.com.</p>
  
  <p>I checked all sql querys in the according sql files, they all seem to work out.</p>
  
  <p>hope you can help :)</p>
