OVHcloud Email answers for the company's own mail rules, so the checker treats every domain on its own: it offers a random address first, and if that is accepted the domain is catch-all and results come back risky ("Accepts all addresses"). Otherwise your address gets a per-mailbox answer. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.

Our checker probes each domain on its own: it offers a random address that can't exist first, and a domain that accepts it comes back risky as catch-all; otherwise your address gets a per-mailbox answer.

OVHcloud sets one MX list for several mail products
OVHcloud publishes one MX list for MX Plan, Email Pro, Exchange and Zimbra, with mx0.mail.ovh.net first and mx4.mail.ovh.net last. It adds that its servers have antispam and antivirus built in.
The redirections guide describes a redirection as one specific From address sent to a To address. We found no catch-all feature in it, so we make no claim either way. Run a catch-all check per domain.
What our checker does behind OVHcloud Email
SimpleVerifier doesn't skip or special-case OVHcloud Email. For each company domain it offers a random address that can't exist, then your address, and disconnects without sending. If the random address is accepted, the domain is catch-all and its results come back risky with "Accepts all addresses". If it is rejected, your address gets a real answer for that mailbox.
Consumer mailboxes are a separate case; see the Gmail and Yahoo pages. Domains behind OVHcloud Email are treated like any company domain.
Cleaning a list full of OVHcloud Email domains
Split the list by domain, not by platform. Two companies on OVHcloud Email can behave in opposite ways, so a catch-all result at one says nothing about the next. The bulk catch-all checker finds which domains in a list accept everything before you spend time on single addresses.
For catch-all domains, keep addresses with recent replies or sign-ups and send the rest in a small first batch, suppressing anything that hard-bounces. For per-mailbox domains, trust the verdict: invalid addresses will bounce, and valid ones were accepted by the company's own directory. Accept-all vs unknown results covers the difference.
Common questions
- Can you verify addresses at domains behind OVHcloud Email?
- It depends on the company. Domains behind OVHcloud Email are probed like any other. OVHcloud Email answers for the company's own mail rules, so the checker treats every domain on its own: it offers a random address first, and if that is accepted the domain is catch-all and results come back risky ("Accepts all addresses"). Otherwise your address gets a per-mailbox answer. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.
- How do I know if a company uses OVHcloud Email?
- Look up the domain's MX records. A first MX host ending in mail.ovh.net means mail goes through OVHcloud Email. The email provider lookup and MX lookup tools show it for any domain.
- Are domains behind OVHcloud Email catch-all?
- Some are and some aren't; it depends on how each company configured OVHcloud Email. A verifier can tell by offering a random address that can't exist: if the domain accepts it, the domain is catch-all and single addresses there can't be confirmed.
- What is mail.ovh.net in an MX record?
- It is the OVHcloud mail host family. OVHcloud tells customers of MX Plan, Email Pro, Exchange and Zimbra to use mx0 to mx4.mail.ovh.net.
