Hi there,

Would be nice to replicate the query on the 2nd DNS configured if the first one timeout, like when SERVFAIL happens checkdmarc will execute the same request and mention it in the Warnings section for example.

I query thousands of domains with an Azure machine and I have some that timeout with 1 sec configured but even with 10 seconds configured, timeout happens. This feature will help me to reduce the time of the total scan by decreasing my timeout.

Keep me advised if you like the idea!
