Hello,

where it is possible to change the Return-Path field in the header of the message when users send email messages to a distribution list ?
This for a users send email into the list ditribution don't receive nondelivery reports (NDRs) but only all owner distribution list.

thank you very much

Ms exchange provides this option with the command :

Set-DistributionGroup "<DistributionGroupName>" -ReportToManagerEnabled $true

The Zeta Alliance crowdfunder `Zimbra Mailinglists` has found a way to set the correct Return-Path on a DL.

Basically what I do is filter the original message with Milter and discard it. Before discarding I take some headers and the body from the mail and place them in a new mail and toss that to the DL with sendmail.

The result is a clean message from the correct domain, and it should be able to pass SPF/DKIM and all that.

Its great, because the final message that goes to the recipients is still processed by Zimbra as a normal DL message.
