The problem still exists. When a DKIM signed mail is sent to a cPanel mailman recipient with DKIM reject option enabled it fails because the mailman changes the message before the DKIM be checked. We need that the cPanel to change the DKIM validation to happen before the "mailman_virtual_router" to avoid changes in message and broke the DKIM validation and to do not check the DKIM again when the mailman tries to delivery to the list members.

  Hello :) Some email providers such as Google and Yahoo have implemented DMARC standards that result in the behavior you have reported. The Mailman developers have introduced an option in the mailing list administration page to address this issue. The option is titled: "Replace the From: header address with the list's posting address to mitigate issues stemming from the original From: domain's DMARC or similar policies." You can configure this option to "Wrap Message" to address the issue. Thank you.
