If you are worried about your ability to validate DKIM signatures tomorrow on emails you own today, you can work-around this by timestamping the emails via something like opentimestamps.org. This would prove that those emails and their DKIM signatures existed today. The next step would be proving that nobody has leaked server's DKIM private keys before the date of timestamping. |
