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
