Is 365boxmail.com a Disposable Email Domain? MX and List Check

Updated 1 November 2026 · Volt Ghost team

365boxmail.com at a glance

We read the DNS records through Cloudflare's public DNS-over-HTTPS resolver and looked up the IP ranges in the regional internet registry. The list status comes from the copy of the open-source disposable email domains list that ships with our checker, and the date comes from that project's public Git history, where 365boxmail.com arrived in one change together with six other domains.

Not a Microsoft 365 mailbox

The "365" in the name can make an address like [email protected] look like a business mailbox. The DNS says otherwise. A domain that really uses Microsoft 365 points its MX record at a host ending in mail.protection.outlook.com (see our Outlook and Microsoft MX records page). 365boxmail.com points at generator.email, and its SPF record simply includes the registrar Porkbun's own SPF list (_spf.porkbun.com) and ends in a soft ~all. The domain sits on Porkbun's name servers and its web address resolves to Porkbun's servers rather than a site of its own, which is how a domain bought only for its mail usually looks.

One mail host, hundreds of domains

On 1 November 2026 we looked up the MX record of every one of the 9,894 domains on our copy of the list. Here is how 365boxmail.com's mail host compares:

generator.email and emailfake.com are themselves on the list, and both receive their own mail through the same host, mx.add5000.com. The DNS alone doesn't prove who runs them, but the pattern is the usual one for temp mail: a small set of receiving servers behind a large, changing pool of cheap domains. Blocking 365boxmail.com by name stops one of those 328 domains. Checking where a domain's MX record points catches the rest of the family, including ones that aren't listed yet.

If you saw @365boxmail.com in your sign-ups

Someone used a short-lived inbox to get past an email check. That isn't automatically abuse; many people do it to keep marketing mail out of their real inbox, and it's legal in most places (see is disposable email legal?). Our guide on how sites detect disposable email covers the trade-offs of blocking, and the email address validator checks syntax, typos and temp mail domains in one go. If you are the one using a throwaway address, don't use it for anything you may need to recover later.
