How T-Mobile receives email (measured 2026-09-05)
Mail sent to t-mobile.com is received by Proofpoint (security gateway), measured 2026-09-05 in our Inbox Rules Index.
T-Mobile publishes a DMARC policy of p=reject, so mail that fails authentication is rejected, a strict SPF record (-all), and no MTA-STS policy.
These are T-Mobile'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 T-Mobile compares with the other domains we measure on the DMARC adoption rate page.
