Hi list
I see a blank response from a list's email from a user ho say he did not sent any response. It seems like an automatic response to a read confirmation, but this response was sent to many lists on our server (triggering moderation alerts on the other lists, and my attention).
Is it possible that the original sender set the 'confirmation request' on the MUA and that request propagated past mailman and got into receiver's MUA?
If yes: Is there a way to intercept and delete these requests on the Mailman host?
Using mailman from Debian 8: 2.1.18-2+deb8u2
Thanks!!

Sorry for the delayed reply - this got buried in my inbox.
To combat this, Mailman removes the following headers from posts delivered to list members:
return-receipt-to disposition-notification-to x-confirm-reading-to x-pmrqc
If you have seen another header that causes some MUA or MTA to return a receipt, please let me know what it is so we can remove that too.

As I said, we try.
