Why can I not send any email?

To avoid spam, remote mail ports (25, 465, 587) cannot be reached from our infrastructure by default. If you need to open the mail ports to send emails, you can enable them from the security group configuration:

Important: The SMTP ports are blocked by default for security reasons. To enable them, complete the identification process (KYC) and upgrade your account to Build level.
  1. Click on Instances, on the left panel of the Scaleway Console.
  1. Click on the Security Groups tab.
  1. Select the security group for which you want to enable SMTP ports.
  1. Tick the checkbox Enable SMTP in the security group information.
The security group settings will immediately be updated on all your virtual instances
