About DMARC records:

DMARC (Domain Message Authentication Reporting & Conformance) records are policies to control emails that fail DKIM &/or SPF checks.

If you want to prevent delivery of emails "from" your domain by unauthorised parties strict SPF is a good start, but if you can sign your emails with DKIM and implement DMARC then you will be in a much better position to prevent spoofed emails and their associated risks.

If DMARC reporting is enabled you may see examples in the reports of spoofed emails being refused by DMARC capable mx.
You list the reporting mechanism and URI in the type of record this check is for, but if you want a domain to receive DMARC reports for different domain(s) then you need an additional record in the report receiving domain's public DNS.

RFC7489 has more info about DMARC
