Is 123mails.org Disposable? Yes: a deepmails.org Temp Domain

Updated 11 November 2026 · Volt Ghost team

123mails.org at a glance

Records come from Cloudflare's DNS-over-HTTPS resolver, the address owner from ARIN's RDAP service, the registration date from the .org registry's RDAP, and the listing date from the Git history of the open-source disposable email domains list.

Where the mail actually goes

123mails.org has almost no DNS of its own: no website, no SPF, no DMARC. The single MX record hands everything to mail.deepmails.org. That host belongs to deepmails.org, a temp mail site whose page title on the day we checked read "临时邮箱 - 临时谷歌邮箱 - 免费Gmail" (temporary mailbox, temporary Google mailbox, free Gmail). deepmails.org's own SPF record, v=spf1 ip4:47.251.66.253 -all, names exactly the address its mail host resolves to, so the receiving server and the brand line up.

The domain was registered in August 2024 and only reached the list in February 2026, about 18 months later. A listing date tells you when maintainers caught a domain, not when it started taking throwaway mail.

The February 2026 batch, nine months on

123mails.org arrived in one change of 12 domains, merged under the title "add more deepmails.org domains". When we re-read the MX record of all 12 on 11 November 2026, the batch had split in two. Six, including 123mails.org and deepmails.org itself, still pointed at mail.deepmails.org. The other six now pointed at mail.temporary-mail.net.

That move matters less than it seems, because both mail host names resolve to the same address, 47.251.66.253. So does mail.linshiyouxiang.net. temporary-mail.net (listed since June 2020) describes itself as "Temporary Mail (Formerly MailTicking)", and linshiyouxiang.net has been listed since May 2019. In our 10 November scan of the whole list, 15 listed domains reached this one machine through those three names. A block rule written for the host name mail.deepmails.org would have missed half the batch; one written for the server address would not.

This is the same pattern we saw with 10mail.xyz and dropmail.me: several brands, one set of receiving servers. Checking a domain's MX records, and the address behind them, is the second signal that keeps working when a service renames its mail host. Services rotate the other way too: the mail.tm server page follows one service that keeps the same server and swaps the public domain it hands out.

If you see @123mails.org addresses

Someone used a temp inbox, usually to collect one verification code. That is not automatically abuse, and in most places it is legal (see is disposable email legal?). If the account unlocks something worth farming, such as free credits, gate that rather than the sign-up itself. And if you are the one using a throwaway address and the code never arrives, our guide to a verification code not received walks through the usual causes.

Look up a domain

Check one name at a time: is it disposable, who hosts its email, or what its MX records say.
