Business mail server and email infrastructure setup
Some businesses need their own mail server or sending infrastructure: for data control, high volumes, several brands, or integration with their own systems. Running one well takes more than installing the software.
The short answer
We design and set up business mail servers and custom email infrastructure: on your own server or cloud, with correct reverse DNS, TLS encryption, SPF, DKIM and DMARC, spam and virus filtering, secure relaying, IP reputation warm-up, backups and monitoring. Or, if a hosted service suits you better, we tell you so.
What’s included
- Design: what to host yourself, and what to leave to a provider.
- Server setup on your hardware or cloud, secured and updated.
- Reverse DNS, TLS, SPF, DKIM and DMARC for every domain.
- Inbound filtering for spam and viruses.
- IP warm-up: building a sending reputation gradually.
- Backups, monitoring and documentation.
How we do it
- Assess your needs, volume and constraints.
- Design the infrastructure.
- Build and secure it.
- Warm up sending and test delivery.
- Hand over with monitoring and documentation.
Is your own mail server right for you?
- Yes, if you need data to stay on your own servers, send at high volume, run several brands, or integrate deeply with your own systems.
- Probably not, if you’re a small team that just needs reliable mailboxes: Google Workspace or Microsoft 365 is easier and cheaper to run.
What the providers expect from servers
Google asks senders to have valid forward and reverse DNS and to use TLS, alongside authentication [1]. A new server’s IP also has no reputation yet, so sending must start slowly and grow, or messages will be filtered.
Common questions
Can a small business run its own mail server?
It can, but it takes ongoing care: updates, security, reputation and backups. We’re honest about when a hosted service is the better choice.
Why do emails from a new server go to spam?
A new IP has no sending history. It needs correct DNS, authentication and a gradual warm-up.
Do you maintain the server after setup?
We can, under a separate maintenance agreement.
