Not really, for two reasons: - X-Original-From is widely used, but isn't really a standard header. - From-munging breaks end-to-end attestation, so we consider x-original-from and similar headers a potential impersonation attempt and ignore them. I would generally say that From-munging isn't a great option for any list that receives patches. A much better approach is to just not modify the message headers or message body. This should be possible with mailman. -K
