Yes. You can verify any @Dhs.gov address in real time with a direct SMTP handshake that provides 99.7% accuracy. Dhs.gov is operated by Department of Homeland Security, runs 2 mail servers, enforces 3 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
dhs.gov publishes 2 MX records. The primary mail exchanger is mxb-00376703.gslb.gpphosted.com, hosted by Proofpoint, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | mxb-00376703.gslb.gpphosted.com | 67.231.155.98 | Reachable |

220 mx0f-00376703.gpphosted.com ESMTP mfa-m0231304Yes. dhs.gov is a valid email domain, operated by Department of Homeland Security. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Dhs.gov's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.

Dhs.gov is Department of Homeland Security, registered through get.gov and first seen Jul 1, 2002.
The domain dhs.gov belongs to the U.S. Department of Homeland Security (DHS), the federal cabinet department responsible for public security. Headquartered in Washington, D.C., DHS oversees border security, cybersecurity, immigration enforcement, disaster response, and counterterrorism through agencies including FEMA, CBP, ICE, TSA, and CISA.
As a federal .gov domain and the parent department of CISA itself, dhs.gov fully implements DMARC, SPF, and DKIM in compliance with Binding Operational Directive 18-01. DHS is a prime target for sophisticated phishing campaigns, and its domain is frequently impersonated in scams related to immigration, security alerts, and emergency notifications.
DHS mail servers do not operate as catch-all systems. The SMTP infrastructure employs strict recipient validation, rejecting messages to nonexistent addresses at the connection level. As the department responsible for national cybersecurity, DHS applies the most rigorous rate limiting, greylisting, and threat filtering to inbound email.
Delivering email to dhs.gov requires the highest standards of authentication compliance. DHS email gateways apply advanced content filtering, malware sandboxing, and multi-layered sender verification. Full SPF, DKIM, and DMARC alignment with a strong sender reputation is essential for any delivery attempt to DHS addresses.
