Can't receive emails since I've move the server

Scaleway block outgoing SMTP connections, it’s in their FAQ:

I cannot send any email.

To avoid spam, remote mail ports (25, 465, 587) cannot be reached from our infrastructure. If you need to open the mail ports to send e-mail, you can go to the advanced options section of your server and change the security group configuration:

  1. On the left panel of the Control Panel, click on “Security”
  2. Select the Security group you want to unblock remote mail ports
  3. Set “Block SMTP” to No.
  4. Reboot your server from the control panel to apply the changes

You could also as an alternative change the SMTP port number to 2525 as SparkPost support this port.
