TITLE:
Plesk issues an incorrect warning that a CNAME doesn't resolve
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:Plesk 17.8 / CentOS
PROBLEM DESCRIPTION:After adding a CNAME-record for a TXT-record and updating the DNS-settings Plesk will test the existence of an A-record for these CNAMEs and when these do not exist it will incorrectly warn me that it doesn't resolve.
CNAMEs are not only used for A-records, but also for TXT-records.
STEPS TO REPRODUCE:CNAMEs are not only used for A-records, but also for TXT-records.
Add a CNAME that only resolves to a TXT-record and then update the settings
ACTUAL RESULT:A warning is given that the CNAME does NOT resolve

It should also test if the target resolves as a TXT-record, not only an A-record.
If that resolves it should keep quiet.
Only issue a warning if neither an A-record or a TXT-record resolves (maybe more types, but this is a realistic situation).
ANY ADDITIONAL INFORMATION:If that resolves it should keep quiet.
Only issue a warning if neither an A-record or a TXT-record resolves (maybe more types, but this is a realistic situation).
