This guide is written for customers using our KVM VPS services and focuses on safe, practical actions.
How to Request SMTP Review for a VPS is usually easiest when you prepare the affected service details first and make changes in a deliberate, reversible way.
- Console and network access should be verified soon after provisioning.
- Apply updates and baseline security hardening before deploying production workloads.
- Keep a record of IP addresses, hostname, operating system, and access method.
- Outbound SMTP behaviour is reviewed carefully because mail abuse can affect service reputation.
- Do not assume unrestricted port 25 access on new VPS services.
For service reputation and abuse prevention reasons, outbound TCP/25 is not assumed to be open by default on VPS services and may require review.
If you lose network access or make a change that prevents remote login, use console access first and include exact error messages if you need support assistance.
