Common Questions About opm.gov

Is opm.gov a disposable or temporary email provider?
No. opm.gov is not a disposable email provider. It is classified as Government Email operated by Office of Personnel Management and addresses on opm.gov are persistent rather than throwaway. Mail sent to a valid opm.gov mailbox reaches a real recipient.
How do I verify if a opm.gov email address is valid?
The fastest way to verify a opm.gov email address is to use our free email checker. Enter any @opm.gov mailbox at the top of this page and our system performs a real-time SMTP handshake against opm.gov'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 opm.gov email exists without sending a message?
Yes. Our real-time email verification API connects directly to opm.gov'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 opm.gov mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for opm.gov?
opm.gov currently publishes 1 mail exchange (MX) record. The primary MX is opm-gov.mail.protection.outlook.com, which is the first server contacted when other mail systems try to deliver email to a opm.gov 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 opm.gov.
Does opm.gov use SPF, DKIM, and DMARC email authentication?
opm.gov 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 @opm.gov is genuine, and opm.gov's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to opm.gov bounce or get blocked?
Bounces from opm.gov 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 opm.gov'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 opm.gov's receivers trust you.
How can I verify a large list of opm.gov email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of opm.gov addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, opm.gov 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 opm.gov email addresses?
Yes, with normal hygiene. opm.gov is a legitimate email service and signups from @opm.gov 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 opm.gov by default.
What email format does opm.gov use for usernames?
Most opm.gov mailboxes follow common patterns like first.last@opm.gov, firstinitiallast@opm.gov, or first@opm.gov, but the actual local-part rules depend on Office of Personnel Management. The only reliable way to confirm whether a specific @opm.gov 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 opm.gov risk score calculated?
The 0-to-100 risk score for opm.gov 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 opm.gov score is recomputed on every audit so it always reflects the live state of the domain.
