Hello,

I'm trying to filter messages that are response to Disposition Notifications.

I've seen that this kind of messages contains the following header:

Content-Type: multipart/report;
report-type=disposition-notification;
boundary="----=_NextPart_000_015A_01C7A9BD.EA993250"

So I've tried to filter incoming messages by Content-Type header

1st, I've created a new PostMaster X-Header to be scanned for Content-Type header

2nd, I've created the following PostMaster Filter rule, that is processed for first

Corrispondenza: Intestazione (header) 1: Valore:

Impostazione: Intestazione (header) 1: Valore:

But I've got no result, the filter is not applied.

Can someone tell me why this is not working?

Or alternatively suggest a better method?

I need to filter and ignore messages that are replies to Disposition notifications

Thank you for any help
