mail.tm Domains: 91 Disposable Domains That Use mail.tm

Updated 2 November 2026 · Volt Ghost team

The server at a glance

DNS records come from Cloudflare's DNS-over-HTTPS resolver, the address owner from RIPE, and the current domain from mail.tm's public /domains endpoint. mail.tm itself is on the list too, but its own mail goes to Yandex rather than to in.mail.tm. The domains that matter for blocking are the ones it hands out for inboxes.

Aged domains, not fresh ones

Most temp mail hosts use cheap new domains. mail.tm's look like old business and hobby sites, with names such as frederictonlawyer.com, belgianairways.com or 2200freefonts.com. The registries confirm the age. These are the first-registration years for all 91 domains:

The oldest are internetkeno.com (1998-04-17) and tiffincrane.com (1998-07-14). An old registration date makes an address look established to a simple "domain age" check, which is one reason sites can't rely on age alone. A registration date only shows when the domain was first created, not who owned it in between, so treat the history as unknown.

When they were listed

59 of the 91 domains were added to the open-source disposable-email-domains list in one change on 10 September 2025 titled "Add mail.tm domains". The rest arrived one or two at a time between 2021 and October 2026. mail.tm rotates what it offers, so its live domain is often not on any list yet: on 2 November 2026 its only public domain, fldubai.com, had been added upstream two days earlier but wasn't in the copy our checker ships. A quick MX lookup catches it anyway, because its MX record is in.mail.tm.

Using mail.tm, or seeing it in your sign-ups

If you use mail.tm, the same rule applies as with any temp inbox: don't use it for an account you may need to recover, because the domain can stop working. Our when not to use temp mail guide lists the cases. If you run a sign-up form, an MX check for in.mail.tm is more reliable than a list of names, and the email address validator checks syntax and listed domains in one pass.
