We have taken our email suite from a third-party, is it a challenge?
It's not a challenge with KDMARC as you just need to add the records once in the DNS. Once that's done, you can control it all from the tool. In other DMARC tools, you need to go back to the DNS to even change SPF and DMARC records. Also, in the case of a third-party email suite, only the third-party has access to the DNS most of the time. Thus, KDMARC can prove to be a very convenient tool.
