msn.com Email Authentication SPF · DKIM · DMARC
SPF
Sender Policy Framework. A DNS record listing which servers are allowed to send mail for this domain. Receivers reject or flag mail from unauthorized servers.
Pass
TXTv=spf1 include:spf.protection.outlook.com include:spf-a.hotmail.com include:spf-b.hotmail.com include:spf-c.hotmail.com include:spf-d.hotmail.com include:_spf-ssg-a.microsoft.com ~all
Authorized senders are defined and pass SPF policy.

DomainKeys Identified Mail. The sending server cryptographically signs outbound mail with a private key, and receivers verify the signature using a public key in DNS.
Pass
SELECTORDetected via standard selectors
A DKIM signature was detected. Outbound mail from this domain can be cryptographically verified.
DMARC
Domain-based Message Authentication, Reporting & Conformance. Tells receivers what to do when SPF or DKIM checks fail: none, quarantine, or reject.
None
TXTv=DMARC1; p=none; sp=quarantine; pct=100; rua=mailto:d@rua.agari.com; fo=1

Common Questions About msn.com
Is msn.com a disposable or temporary email provider?
No. msn.com is not a disposable email provider. It is classified as Free Email Provider operated by Microsoft Corporation and addresses on msn.com are persistent rather than throwaway. Mail sent to a valid msn.com mailbox reaches a real recipient.
How do I verify if a msn.com email address is valid?
The fastest way to verify a msn.com email address is to use our free email checker. Enter any @msn.com mailbox at the top of this page and our system performs a real-time SMTP handshake against msn.com's mail servers, confirming whether the mailbox exists, is reachable, and is safe to send to. No email is ever delivered during the check.
Can I check if a msn.com email exists without sending a message?
Yes. Our real-time email verification API connects directly to msn.com's mail server, opens an SMTP session, and queries the mailbox using the RCPT TO command without ever transmitting an actual email. The server's response confirms whether the msn.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for msn.com?
msn.com currently publishes 1 mail exchange (MX) record. The primary MX is msn-com.olc.protection.outlook.com, which is the first server contacted when other mail systems try to deliver email to a msn.com address. The full list with priorities and IP addresses is in the MX Records panel above. MX records tell sending servers where to route email for msn.com.
Does msn.com use SPF, DKIM, and DMARC email authentication?
msn.com enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: none). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @msn.com is genuine, and msn.com's DMARC policy of 'none' instructs receivers how to handle messages that fail those checks.
Why do emails to msn.com bounce or get blocked?
Bounces from msn.com usually fall into three buckets: the mailbox doesn't exist (5xx user unknown), the inbox is full, or your sending domain isn't authenticated to msn.com's satisfaction. The fastest fix is to run each address through a free email verifier before you send, and to make sure your own SPF, DKIM, and DMARC are configured correctly so msn.com's receivers trust you.
How can I verify a large list of msn.com email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of msn.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, msn.com catch-all detection, role-account detection, and disposable-domain matching. Results typically come back within minutes and previously-failed addresses on your blacklist are reprocessed for free. For continuous high-volume needs, see our unlimited email verification API.
Is it safe to accept signups from msn.com email addresses?
Yes, with normal hygiene. msn.com is a legitimate email service and signups from @msn.com behave like any other real user. Pipe each address through a real-time email verifier API at the moment of signup to catch typos and dead mailboxes, but there is no need to block msn.com by default.
What email format does msn.com use for usernames?
Most msn.com mailboxes follow common patterns like first.last@msn.com, firstinitiallast@msn.com, or first@msn.com, but the actual local-part rules depend on Microsoft Corporation. The only reliable way to confirm whether a specific @msn.com address exists is to run it through a free email verification tool. Guessing patterns will produce a high bounce rate and damage your sender reputation.
How is the msn.com risk score calculated?
The 0-to-100 risk score for msn.com combines disposable-domain classification, mail-server reachability, MX record presence and depth, SPF / DKIM / DMARC enforcement, DMARC policy strength, SMTP banner response, and domain age. Lower scores mean safer to send to. Disposable domains are pinned at the high end of the scale. The msn.com score is recomputed on every audit so it always reflects the live state of the domain.
Is msn.com a valid email domain?
Yes, msn.com is a valid email domain operated by Microsoft Corporation. Originally part of the MSN portal, it now runs on Microsoft's Outlook.com/Exchange Online infrastructure.
Is msn.com a disposable or temporary email provider?
No, msn.com is not a disposable email provider. It is a legacy permanent Microsoft email domain, now part of the unified Outlook.com platform.
What mail server does msn.com use?
MSN.com uses Microsoft's Exchange Online Protection servers, shared with outlook.com, hotmail.com, and live.com. All Microsoft consumer email domains use the same backend.
Can I send marketing emails to msn.com addresses?
Yes, with proper consent. MSN.com addresses use the same Microsoft spam filtering as other Microsoft domains. Maintain proper authentication and sender reputation.
How do I verify an email address at msn.com?
MSN.com addresses are verified via SMTP through Microsoft's infrastructure. The same rate limiting and verification behavior as outlook.com applies.
