Is it possible to create multiple CNAME records in Plesk Automation 11.5 like?
mail.example.com CNAME a.mailhost.net mail.example.com CNAME b.mailhost.net
Is it possible to do it in PA 11.5?
Multiple CNAME records for the same fully-qualified domain name is a violation of the specs for DNS.
According to RFC-1034:
If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types.
Plesk automation 11.5 does not allow to create multiple CNAMES for the same fully-qualified domain name.
