QQ Mail MX Records: qq.com and foxmail.com Mail Servers

Updated 14 November 2026 · Volt Ghost team

Three hosts, numbered backwards

Read through Cloudflare's DNS-over-HTTPS resolver on 14 November 2026. All three QQ Mail domains returned the same set.

The names run opposite to the priorities: mx3 carries the lowest number, so it is the preferred server and mx1 is the final fallback. Anyone who reads only the host names may assume mx1 is primary; the priority value is what counts. Every host has at least one IPv6 address, so an IPv6-only sender can still deliver. Large providers may answer differently depending on where you resolve from, so treat the counts above as one vantage point.

SPF and DMARC across the three domains

• Nested SPF: spf.mail.qq.com pulls in seven further lists (three named qq-a/b/c, four named biz-a/b/c/d) and ends in -all, while the apex records end in the softer ~all.
• No MTA-STS or TLS-RPT: none of the three domains published _mta-sts or _smtp._tls records, unlike Gmail, so senders are not told to insist on TLS.
• Mixed DMARC: a forged foxmail.com sender gets the lighter treatment. If you filter on DMARC results, expect foxmail.com failures to arrive flagged rather than quarantined.

When these records matter

QQ addresses show up on sign-up forms from China and from overseas Chinese users. If a confirmation or one-time code to an @qq.com address never arrives, the bounce or deferral normally names one of the three hosts above; mail that is accepted but never shown is usually sitting in the recipient's spam folder. Our verification code not received checklist covers both cases. A custom business domain whose MX ends in .qq.com is on Tencent's hosted mail; the email host lookup now labels that as QQ Mail (Tencent).

QQ Mail and disposable-address checks

An MX-based filter sees Tencent's own servers and lets qq.com through, which is right: it is a permanent mailbox. Throwaway domains look different. 365boxmail.com, for example, has a single MX pointing at generator.email, a host shared by hundreds of listed temp mail domains. For the other signals sites use, read how sites detect disposable email, or test one address with the disposable email checker.
