• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

DKIM Plesk 12

The above thread didn't help.
I have CentOS 7 and Plesk 12.

When enabling "Use DomainKeys spam protection system to sign outgoing email messages" from domain's Mail settings, in domain's DNS appear two TXT records:
_domainkey.domainname.com. TXT o=-
default._domainkey.domainname.com. TXT p=xxxxxxxxxxxxxxxxxxxxxxxx;

but the e-mails aren't signed.
Also /etc/opendkim.conf, /etc/opendkim/KeyTable, /etc/opendkim/SigningTable and /etc/opendkim/TrustedHosts files are missing (if we consider that this is the correct way to install DKIM).

Hi quark,

even that the definition "DomainKeys" and "DKIM" have parts in common, these two signing procedures have different installation packages, different paths, different modifications and what is most important, ONLY "DomainKeys" is used by Plesk. If you wish to use "DKIM" as well, you may find some ( working ) solutions over the forum search.

If you wish additional informations and/or help, please provide the used MTA ( qmail or postfix ) and describe your previous steps to install OpenDKIM ( "DKIM" ) on your server, which need some more steps, than only to use "yum install opendkim" to work. As well, mail - logs are usefull to help you to investigate possible failures/issues.

... is for "DomainKeys" and not for "DKIM", please keep that in mind, when checking your configuration(s)/modification(s) with for example "http://www.mail-tester.com/" or "http://www.port25.com/support/authentication-center/email-verification/" after your installation(s)/modification(s).
