Decision: Mailcow goes on Billing VPS (38.68.14.188) not NC1.
Reasoning:
- Clean IP reputation (only Paymenter on this server)
- Sufficient resources (13GB free disk, ~60% free RAM)
- Logical co-location with Paymenter for transactional email
- Frostwall dependency was incorrect — email needs clean IP,
not dedicated hardware
Mailcow is now unblocked and ready to deploy.
