Email invalid if it has no A record


When attempting to use a recovery email, the domain that I use does not have an A record (but has valid mx records) but gets rejected with the following error:

Content: ‘{“type”:“urn:acme:error:malformed”,“detail”:“Error creating new registration :: Validation of contact failed: Server failure at resolver”,“status”:400}’

I don’t believe an A record should be required on the email domain, better to validate mx records only.


Best report that on the ACME servers issue tracker:


Thanks! We’ve got an open issue and are planning to fix it:


Awesome, glad its on your radar.
