facebook.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 redirect=_spf.facebook.com
Authorized senders are defined and pass SPF policy.
DKIM
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.
Reject
TXTv=DMARC1; p=reject; rua=mailto:a@dmarc.facebookmail.com; ruf=mailto:fb-dmarc@datafeeds.phishlabs.com; pct=100
Strict policy. Receivers are instructed to reject any mail that fails SPF or DKIM. The strongest available setting.

About this Domain
About facebook.com
Facebook (facebook.com) is the world's largest social networking platform, now operated by Meta Platforms Inc. The facebook.com domain remains in active use for corporate email alongside the newer meta.com domain. Facebook has over 3 billion monthly active users globally and the platform's advertising business generates the majority of Meta's revenue.
The facebook.com domain maintains strict email authentication with SPF, DKIM, and DMARC enforcement. Facebook is one of the most impersonated brands in phishing attacks worldwide, with fraudulent messages commonly disguised as account security alerts, friend requests, and login notifications. Strong authentication prevents unauthorized senders from spoofing the facebook.com domain.
Email verification against facebook.com returns definitive responses for valid and invalid mailboxes. The domain does not accept mail for non-existent addresses. Facebook's mail infrastructure includes sophisticated anti-abuse measures including strict rate limiting, IP reputation checks, and behavioral analysis of incoming SMTP connections.
For senders communicating with facebook.com addresses, complete email authentication is mandatory. Meta's security team enforces strict incoming email policies across both facebook.com and meta.com domains. Sending domains must have valid SPF, DKIM, and DMARC records with proper alignment, and maintain strong sender reputation for reliable inbox delivery.

Common Questions About facebook.com
Is facebook.com a disposable or temporary email provider?
No. facebook.com is not a disposable email provider. It is classified as Corporate Email operated by Meta Platforms Inc. and addresses on facebook.com are persistent rather than throwaway. Mail sent to a valid facebook.com mailbox reaches a real recipient.
How do I verify if a facebook.com email address is valid?
The fastest way to verify a facebook.com email address is to use our free email checker. Enter any @facebook.com mailbox at the top of this page and our system performs a real-time SMTP handshake against facebook.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 facebook.com email exists without sending a message?
Yes. Our real-time email verification API connects directly to facebook.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 facebook.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for facebook.com?
facebook.com currently publishes 1 mail exchange (MX) record. The primary MX is smtpin.vvv.facebook.com, which is the first server contacted when other mail systems try to deliver email to a facebook.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 facebook.com.
Does facebook.com use SPF, DKIM, and DMARC email authentication?
facebook.com enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: reject). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @facebook.com is genuine, and facebook.com's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to facebook.com bounce or get blocked?
Bounces from facebook.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 facebook.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 facebook.com's receivers trust you.
How can I verify a large list of facebook.com email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of facebook.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, facebook.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 facebook.com email addresses?
Yes, with normal hygiene. facebook.com is a legitimate email service and signups from @facebook.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 facebook.com by default.
What email format does facebook.com use for usernames?
Most facebook.com mailboxes follow common patterns like first.last@facebook.com, firstinitiallast@facebook.com, or first@facebook.com, but the actual local-part rules depend on Meta Platforms Inc.. The only reliable way to confirm whether a specific @facebook.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 facebook.com risk score calculated?
The 0-to-100 risk score for facebook.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 facebook.com score is recomputed on every audit so it always reflects the live state of the domain.
Is facebook.com a valid email domain?
Yes, facebook.com is the official corporate email domain for Meta Platforms Inc.. It is used for business communications and is not available for public registration.
Is facebook.com a disposable or temporary email provider?
No, facebook.com is a corporate email domain belonging to Meta Platforms Inc., used exclusively by employees and authorized personnel.
What mail server does facebook.com use?
facebook.com uses enterprise-grade mail infrastructure. Check the MX records section above for specific mail server details.
Can I send marketing emails to facebook.com addresses?
B2B marketing to facebook.com addresses requires proper consent and compliance with anti-spam laws. Corporate domains may use catch-all configurations, so verify addresses before sending.
How do I verify an email address at facebook.com?
