Disposable Email Domains on DigitalOcean: 866 Listed

On 10 November 2026, 866 domains on our disposable email list had at least one MX server on DigitalOcean, the third-largest network in our count after Hetzner and Oracle Cloud. What sets this group apart is redundancy: 590 of the 866 (68%) publish two or more MX hosts, typically a matched pair on two separate droplets.

Three kinds of tenant

The Wabbly/Wally pair (341 domains). Every one of these domains lists both mail.wabblywabble.com and mail.wallywatts.com. Each host name resolves to two addresses, one at DigitalOcean and one at Hetzner, so the group is split across two providers on purpose. The same domains publish an SPF record that authorises only a private IPv6 range, covered on our SPF on disposable domains page.

One batch, one droplet (114 domains). All 114 domains added to the list in a single change on 22 May 2025 run their own mail. host, and all 114 host names resolve to the same address, 157.230.203.88. One hundred and fourteen different-looking mail servers turn out to be one machine.

Paired MX families (about 240 domains). Several families of host names follow one pattern: two names under the same brand, each on its own droplet. The largest are em4/srv4.rejecthost.com (52 domains), a catchservers pair (45) and a mainnetmail pair (39), followed by brushemail, aerospaceemail, patternemail and two numbered mx host series. Most of their domains were first listed in 2018; a single-host family, mx.generic-isp.com, adds 36 more, all listed in 2018.

The 2025 row is dominated by the 22 May batch (114). The 2026 additions are spread across the year rather than in one burst.

What this means for detection

Network-level blocking would hit DigitalOcean's many legitimate customers, and the redundancy here makes address rules brittle: block one droplet and mail flows through the other. Checking the domain itself is more reliable, which is the approach explained in how sites detect disposable email. For the same view of other providers, see Hetzner, Contabo, OVHcloud; the Hetzner page also ranks the ten biggest networks.

Source: our 10 Nov 2026 MX read of the whole list, with every mail host resolved and matched to AS14061 via Team Cymru's IP-to-ASN data; method details on the Hetzner page. Domains whose MX hosts span DigitalOcean and another provider are counted here and there.

Check one domain

Enter a single address or domain. You will see whether it is listed as disposable and where its mail is delivered; there is no bulk export.

Questions

How many disposable email domains use DigitalOcean?

866 listed domains had an MX server on DigitalOcean's network (AS14061) on 10 November 2026. 476 use DigitalOcean only; 387 also have an MX server at Hetzner.

Why do these domains have two MX hosts?

Most groups here use a matched pair of host names, each on its own droplet, so mail still arrives if one machine is down. It is the same redundancy ordinary companies use, applied to throwaway domains.

Which temp mail groups run on DigitalOcean?

The Wabbly/Wally pair (341 domains), a batch of 114 domains added to the list on 22 May 2025 that all share one address, and about eight families of paired MX hosts listed since 2018, the largest under rejecthost.com.

Can I block disposable email by DigitalOcean IP range?

Not safely. DigitalOcean hosts many legitimate apps and mail servers. A domain list or a per-address lookup catches temp mail without rejecting real users.
