These are Five9's settings for receiving mail, read from public DNS on 2026-09-05. They say nothing about where your own mail lands. A security gateway or Microsoft 365 in front of the mailbox is one of the setups that most often answer catch-all or unknown to a verifier, so verify each address rather than trusting the format alone. Check the live records yourself with our MX lookup, or see how Five9 compares with the other domains we measure on the DMARC adoption rate page.
