Is there any reason why cron emails are not signed by OpenDKIM?
My server is setup so all emails are delivered via postfix (sendmail is disabled). The cron emails are delivered from <user>@mail.example.com. If I manually send an email from "mayhem@mail.example.com", the email is digitally signed by DKIM.
However, the cron emails (using the same email address) do not get signed. I checked the maillog and confirmed Postfix is delivering these cron emails.
Any ideas where to start troubleshooting this?
