Hi,
This seems to be a very basic question and/or issue, but I could not find a reliable for it:
Assume a list member with the email address like (just as an example) joe.student@university.edu sends an email to a list, Mailman gets the email, processes it and would try to send that email to all members with a sender field as: 'joe.student@university.edu'. plus listname@listserver.TLD
Are you referring to the envelope sender or to the From: header?
The envelope sender will be listname-bounces@listserver.TLD or if VERP is enabled, listname-bounces+recipient=recipient.domain@listserver.TLD.
The From: header will be unchanged from the incoming message. If yo want the From: to be the list, you can apply DMARC "Replace From with list address" unconditionally and the From: will look like
From: joe.student via listname listname@listserver.TLD
...
I found some solution:
- Asking the members to add their email to the signature
- manipulating the from field and add the name of the sender as a comment, not that easy, needs some Python code
- manipulating the from files and replacing the @ with something else, not that easy, needs some Python code
- . . .
The DMARC mitigations will do these thing for you.
More important: None of these would allow a simple click on the reply bottom to send the email to the original sender.
And they will add the poster's original From: address to Reply-To:
