disroot.org MX records
disroot.org publishes a single MX host, disroot.org. With no backup host, a sender that can't reach it queues the message and retries until the server answers or the queue gives up.
disroot.org SPF record
The record on 5 November 2026 was v=spf1 a mx -all.
It ends in a hard fail (-all): receivers may reject mail from any server the record does not list.
disroot.org DMARC policy
The record is v=DMARC1; p=reject; adkim=s; aspf=s; rua=mailto:[email protected]; ruf=mailto:[email protected];.
p=reject asks receivers to refuse mail that fails DMARC.
Aggregate reports go to disroot.org, so the domain's owner sees who sends mail as @disroot.org.
What that means for you: if a contact gives an @disroot.org address and you send to them, nothing changes. But never put an @disroot.org address in the From line of mail sent through your own tool or ESP. It can't pass DMARC for disroot.org, and this policy tells receivers to refuse it.
disroot.org TLS policy
_mta-sts.disroot.org publishes v=STSv1; id=pT6lFCnOH;, so disroot.org uses MTA-STS: sending servers that support it must deliver over verified TLS or not at all (RFC 8461).
It also asks for TLS reports with v=TLSRPTv1;rua=mailto:[email protected] (RFC 8460).
Can you verify @disroot.org addresses?
Our checker treats @disroot.org like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not published a test of how disroot.org answers for @disroot.org, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
