How CSX receives email (measured 2026-09-05)
Mail sent to csx.com is received by Microsoft 365 (mailbox provider), measured 2026-09-05 in our Inbox Rules Index.
CSX publishes a DMARC policy of p=none, which only monitors, a strict SPF record (-all), and no MTA-STS policy.
These are CSX'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 CSX compares with the other domains we measure on the DMARC adoption rate page.
