What checkout does not erase

Email is still an account object. A personal inbox and a named domain still link workloads. Crypto settlement removes the card processor; it does not rewrite DNS history.

PTR and mail

Editable PTR is included. Warm reputation yourself. Port 25 is open; we do not run your MTA. Align A/AAAA, PTR and HELO before you send.

Panel tickets only

All support is handled exclusively through tickets in the client panel. Include invoice code or IP. Do not paste root passwords.
