Question
How to enable/disable DKIM signing for all domains in Plesk for Linux?
Answer
-
Connect to a Plesk server via SSH.
-
Allow signing outgoing mail by DKIM spam protection on a server level:
# plesk bin mailserver --sign-outgoing-mail true
-
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.

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).
I have executed the 3rd command with "false" and then run again with "true". But gmail saying my server domain email's DKIM is "FAIL". How to fix it please? Can we regenerate new Key domain domains?
