DKIM issue on internally-generated bounce messages
Hi, we have noticed a issue on DKIM internally-generated bounce messages. If a our user have a overquota mailbox the bounce message is not DKIM signed although this is configurated.
For example : user over quota example@example.com, buone message from support@hostingtek.it (on this domain DKIM is correctly configurated), the bounce message is not DKIM signed. We attach sample emails
We have a standard multiserver ispconfig setup
