On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Question

How to enable/disable DKIM signing for all domains in Plesk for Linux?

Answer

  1. Connect to a Plesk server via SSH.

  2. Allow signing outgoing mail by DKIM spam protection on a server level:

    # plesk bin mailserver --sign-outgoing-mail true

  3. Run the following command to enable DKIM signing for all domains:

    # for domain in $(plesk db -Ne 'SELECT name FROM domains WHERE parentDomainId=0;'); do plesk bin domain_pref --update $domain -sign_outgoing_mail true; done

    Note: To disable DKIM signing for all domains, switch the value to from true to false.

 

Additional Information

    3. Run the following command to enable DKIM signing for all domains:

    for domain in $(plesk db -Ne 'SELECT name FROM domains WHERE parentDomainId=0;'); do plesk bin domain_pref --update $domain -sign_outgoing_mail true; done

    This didn't work for me on CentOS 7 + Plesk 18.

    I get:
    -bash: syntax error near unexpected token `do'

    Hi, Vojkan Cvijanovic!

    The command should work there - please make sure you run it as root and that no extra characters are copied over.

    Thanks

    If you have problems validanting DKIM records first disable all (false) and after enabled all (true).
