Filter "deleted without being read" messages
in [Postfix]
|
From: Denis BUCHER on 12 Aug 2010 12:09 Dear all, Due to bugs in Microsoft Outlook sending "your message was deleted without being read" even when this function is disabled, I need to filter these messages in postfix. The problem is how to be sure to filter only these messages ? 1. It will be very slow if I filter the *body* of all messages on "was deleted without being read on " or "Disposition: automatic-action/MDN-sent-automatically; deleted" ? 2. Therefore does someone know if I can filter something based on a header ? I only found this header that looks interesting : Content-Type: multipart/report; boundary="----_=_NextPart_001_01C9C7DF.11F1ACA6"; report-type=disposition-notification But how to specify this in postfix ? And if it is not necessary, is there a way to say "if this header is present then check the body" ? 3. And on postfix side, I think I have to use header_checks ? Thank a lot in advance for any help, I hope my question is clear ;-) Denis

No, since postfix doesn't scan all the body > Content-Type: multipart/report; > boundary="----_=_NextPart_001_01C9C7DF.11F1ACA6"; > report-type=disposition-notification > > But how to specify this in postfix ?
