Unable to send or receive emails

For your emails to work, you need to have an active email service. If your email solution is linked to a Web Hosting plan, check that it has not expired. You can verify this directly in the OVHcloud Control Panel. The corresponding domain name must also be active.

Start by checking that you are up to date with your payments and service renewals.

Follow these steps to ensure that your relevant services are up and running:

This is an SMTP error return. This indicates that the exchange between the outgoing server and the incoming email server could not be completed correctly. The code is used to determine the type of error the server encountered. It is usually accompanied by a message detailing this error.

An SMTP response consists of a 3-digit number. The three digits of the answer each have a particular meaning:

• The first number indicates whether the answer is positive, negative or incomplete. An SMTP client will be able to determine its next action by examining this first digit.
• The second and third digits provide additional information.

There are four possible values for the first digit of the response code:
