The server at a glance
| Check | Result on 3 Nov 2026 |
|---|---|
Listed domains with MX email.chatgpt.org.uk | 715 |
Listed domains with MX email.gravityengine.cc | 327 |
| Together (one domain uses both) | 1,041 (1,025 with no other mail server) |
| Address of both MX names | 138.226.240.26 (A record; no IPv6) |
| Who holds that range (RIPE) | SOLLUTIUM-NET, 138.226.240.0 to 138.226.240.255, country NL |
| GPTMail website | mail.chatgpt.org.uk, behind Cloudflare |
chatgpt.org.uk | Registered 21 Dec 2022 (Nominet); Cloudflare name servers; its own mail goes to iCloud (mx01/mx02.mail.icloud.com); not on the disposable list |
gravityengine.cc | Registered 1 Jul 2021 (Verisign); Cloudflare name servers; MX email.gravityengine.cc; on the disposable list; its website returned Cloudflare error 526 (invalid origin certificate) |
Records come from Cloudflare's public DNS-over-HTTPS resolver, registration dates from the Nominet and Verisign RDAP services and the IP range from RIPE. Neither MX name publishes SPF or DMARC. That's normal for a receive-only server, but it also means nothing in DNS stops someone sending mail that claims to come from these names.
Two MX names, one address
The link between the two names is more than a shared IP. Domains whose names advertise GPTMail use both: gptmail.webredirect.org points at email.chatgpt.org.uk, while gptmail.cc.cd, gptmail.us.ci and mailchatgpt.eu.cc point at email.gravityengine.cc. If you block by mail server, block both names, or simply the address 138.226.240.26. A rule for only one of them misses about 31% or 69% of the group.
Listed in a rush in June 2026
We matched every domain against the public Git history of the open-source disposable-email-domains project that our disposable domains list is copied from. 841 of the 1,041 were added in June 2026, mostly on three days: 439 on 5 June 2026, 204 on 6 June 2026, 155 on 9 June 2026, nearly all in changes titled "Add missing domains from sources". The change on 5 June alone added 123 email.chatgpt.org.uk domains and 317 of the 327 email.gravityengine.cc domains.
| Month added to the list | Domains now on this server |

| June 2026 | 841 |

The group also shrinks between our checks. On 2 November we counted 724 domains on email.chatgpt.org.uk; one day later 9 of them no longer pointed there, six of them .org names that now have no MX record at all. Expect the numbers on this page to drift.
Hostnames, not just domains
605 of the 1,041 names are subdomains rather than registered domains. The biggest parents are dynv6.net (307), eu.cc (65), cc.cd (30), ccwu.cc (25), indevs.in (17). The biggest, dynv6.net, is a free dynamic-DNS service: anyone can create a hostname under it, so the list can only block the exact names someone reported. Our disposable email checker flags any address on a listed name or below it, but it can't flag a brand-new hostname under dynv6.net, because dynv6.net itself isn't listed. An MX lookup closes that gap: the new hostname's MX still says email.chatgpt.org.uk. For the same pattern on a different server, compare generator.email's domains, which are mostly ordinary registered domains.
If you're using GPTMail
GPTMail's own page pitches it for receiving verification codes. That works until a site blocks the domain or the hostname stops pointing at the server, which, as the overnight changes above show, happens often. Don't use any shared temp inbox for an account you might need to recover. And if a code just never shows up, our guide to a verification code not received goes through the fixes in order.
All 1,041 domains
Every domain on our copy of the list whose MX record included email.chatgpt.org.uk or email.gravityengine.cc on 3 November 2026. 4 more listed names are left out here because they contain profanity; the checker still flags them.

Questions
What is GPTMail?
A free temporary email site at mail.chatgpt.org.uk (its page title on 3 November 2026 was "GPTMail: Free Temporary Email Generator & Temp Mail"). Despite the name, nothing in its DNS records links it to OpenAI or ChatGPT.
How many disposable domains use GPTMail's server?
1,041 domains on our copy of the list on 3 November 2026: 715 with MX email.chatgpt.org.uk and 327 with MX email.gravityengine.cc (one uses both). 1,025 of them have no other mail server.
Are email.chatgpt.org.uk and email.gravityengine.cc the same server?
Both names resolved to the single IPv4 address 138.226.240.26 on 3 November 2026, and domains named gptmail.cc.cd, gptmail.us.ci and mailchatgpt.eu.cc point at email.gravityengine.cc. That is strong evidence of one operator, but DNS alone can't prove who runs a server.
Why doesn't the disposable list catch every GPTMail address?
605 of the 1,041 listed names are subdomains of shared hostname services such as dynv6.net, and those parent zones are not on the list (they also host ordinary sites). A new random subdomain is not flagged until someone adds it, but its MX record still points at the same server.
