Hi! Recently, I came upon a problem without a solution:
If I trigger an autoreply (for example because of vacations), how do I get the system to add a DKIM-header for the proper domain ? This post describes that the recipient of the autoreply can check the signature by looking for the d=<domain> field in the DKIM-Signature header: https://stackoverflow.com/questions/50371039/does-dkim-verify-smtp-envelope-from-or-the-mail-header-from The problem is that the autoreply driver looses the information on which sender is used to send out the mail (envelope-from is <> to avoid mail-loops). Because of the <> envelope-from, how can the proper sender-domain (and dkim key) be found on the sending host ?
