To ensure the highest level of security and maintain the reputation of our network IPs, TCP Port 25 (Outgoing SMTP) is strictly blocked on all virtual and dedicated servers.
Can I request an unblock?
No. We do not unblock port 25 under any circumstances. This policy is in place to prevent spam and protect all customers on our network from being blacklisted by major email providers (like Gmail or Outlook).
How can I send emails from my server?
If your application, website, or server needs to send outgoing emails (like password resets, notifications, or newsletters), we strongly recommend using a reputable third-party SMTP relay or transactional email service.
These services are specifically designed for high deliverability and use alternative ports (like 587, 465, or 2525) or API connections, which are fully supported on our network. Popular options include:
- SendGrid
- Mailgun
- Amazon SES
- Postmark
- Brevo (formerly Sendinblue)
By using a dedicated email service, you ensure your legitimate emails reach your users' inboxes reliably without risking the security of your server.
