The mailing list for listmasters using Sympa

[Ralph Ballier <address@concealed>]

Hello,

I have recipients on the list for whom the following applies:

_dmarc.user.de descriptive text "v=DMARC1; p=reject;"

Emails to them are rejected if the From: header line does not align with the list server.

In Sympa, the workaround is to add "dmarc_protection.mode dmarc_reject" to sympa.conf.
However, this causes all information about the original sender of the email to be lost, and the recipient can only reply to the list.

How can I restore the sender’s address in the header so that the recipient can reply directly to them?

Best Regards

Ralph
