I am trying to save the private key for DKIM but when I save it, it seems to revert to a previous key and I’m unable to save the new private key.
From the DomainKey Options page on Virtualmin, I select the option ‘Use key below’, I copy and paste the new private key in and click ‘save’ and get the following message:
Using custom DKIM key …
Adding DKIM records to DNS domain mailer.autopo.st …
… records already exist
When I go back, it still has the previous private key in it and won’t save the new one.
I’m guessing that this is the cause of this response from www.mail-tester.com
The DKIM signature of your message is:
v=1; a=rsa-sha256; c=simple/simple; d=mailer.autopo.st; s=2016; t=1481537938; bh=VR4Gv7+sAJCtputRxtsJtzZuBdFThBnF0V+Eq01WakM=; h=Date:To:From:Reply-To:Subject:List-Unsubscribe:From; b=...
Your public key is:
Key length: 2048bits
Your DKIM signature is not valid
Is there are reason that my new private key is not saving?
Thank you in advance for any help.
