Invalid RUA addresses inflate bounce rates, disrupt DMARC reporting, and demonstrate disregard for email security and ecosystem responsibility.

Invalid DMARC RUA Addresses Should Be Penalized

Email providers like Google and Microsoft should enforce penalties for companies implementing invalid RUA email addresses in their DMARC policies.

Sending reports to invalid addresses unnecessarily inflates bounce rates for reporters, potentially degrading their email-sending reputation and disrupting infrastructure.

Invalid RUA addresses signal a disregard for email security standards. This negligence not only undermines the effectiveness of DMARC reporting but also creates broader security risks for the Internet community.

Those failing to implement valid RUA email addresses demonstrate a lack of commitment to email ecosystem integrity and the collective effort to combat abuse.
