    What is not mentioned is how you obtain the public key to publish in DNS. The article does mention; "if external DNS provider is used, contact your DNS owner in order to add DKIM record" ... but it would help to know what the public key is to add :-)

    Thanks Ivan Postnikov. Indeed I found and used that article, but it would be worth including at least a link this this in the main article here as you can't enable DKIM without publishing the selector key and so it really needs to be a part of the solution :-)

    I have a serious problem.
    I'm on Obsidian 18.0.29 Update 2

    I have several domains under the same subscription. I set up DKIM for all of them.

    They work fine when sending email from an email client.

    But when I send an email using PHP from any domain other than the first one I added to this subscription, it fails with the error "DKIM: Fail with domain: (primary domain)"

    How do I get PHP to send as the right domain and use the right DKIM?

    Hello Kathy Sechrist

    As I can see, you've already found the article https://support.plesk.com/hc/en-us/articles/115002513925 and left an additional question there.

    We'll check that additional question.
