Allow underscore in CNAME entries when configuring DNS/DKIM in Plesk Automation 11.5.
When you try to add a CNAME record with underscore ("_") in the begining of it (usually for DKIM records), you receive an error message, telling that non-latin characters are not allow.

Please note that Plesk Automation is a product of Ingram Micro company.
The same bug was confirmed in Plesk and it was fixed since version Plesk Onyx 17.5.3 Update 46 (PPPM-4301) and Plesk Onyx 17.8.11 Update 1 (PPP-34267). Let us know if you have any feedback.
