hotmail.fr email servers, SPF and DMARC

hotmail.fr publishes a single MX host, eur.olc.protection.outlook.com. 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.

52 other domains we checked on the same day also hand their mail to Microsoft Outlook.com (consumer) servers, with different records from hotmail.fr: hotmail.ca, hotmail.cl, hotmail.co.in, hotmail.co.jp, hotmail.co.kr, hotmail.co.nz, hotmail.co.th, hotmail.com.ar and 44 more.

The record on 5 November 2026 was v=spf1 include:spf2.outlook.com ~all.

In plain terms, it delegates to spf2.outlook.com. The top level uses 1 DNS-querying term; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).

It ends in a soft fail (~all): mail from unlisted servers should be accepted but treated as suspicious.

The record is v=DMARC1; p=none; rua=mailto:[email protected];ruf=mailto:[email protected];fo=1:s:d.

p=none only asks for reports; failing mail is delivered as normal.

Aggregate reports go to dmarc.microsoft, so the domain's owner sees who sends mail as @hotmail.fr.

46 other domains published exactly the same MX hosts and SPF record as hotmail.fr on 5 November 2026: hotmail.at, hotmail.be, hotmail.ch, hotmail.co.il, hotmail.co.za, hotmail.com.tr, hotmail.de, hotmail.dk, hotmail.es, hotmail.fi, hotmail.gr, hotmail.hu and 34 more. Mail to any of them lands on the same servers.

These are Microsoft's consumer mail servers, and Microsoft is currently refusing mailbox checks from our server's network (see the Outlook.com page). Expect @hotmail.fr results to come back risky rather than valid or invalid; syntax, MX, disposable and role checks still run.

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.
