Overview

By default, port 25 is blocked across our infrastructure, and email sending is not permitted on virtual or cloud servers. If you need to send email, we recommend using a third-party SMTP provider such as Amazon SES. Outgoing email is allowed on our website hosting by default. If you have a valid use case and need port 25 unblocked, please open a support ticket and include the following:
  • A link to your website or project, if applicable
  • A clear explanation of why you require port 25 access
  • Examples of the types of emails you intend to send
If your account is found to be sending unsolicited or abusive email after port 25 is unblocked, it will be blocked again, and future unblocking requests will not be considered across any of your current or future services. Exceptions may be made only for resellers or customers operating shared environments, such as web hosting platforms.
