Mail hosting

Business email for our own domains, run on our own servers.

Webmail for a demo mailbox: the inbox on the left and an open message from the workshop on the right.
The shared calendar in webmail: one week with planning, a workshop booking, a backup restore test and a team lunch.A delivery test of a message sent from our mail server: a score of 10 out of 10, properly authenticated.

Demo data.

Our business email runs on our own mail server, not on a big provider's cloud. One server carries mail for several of our domains, with webmail, calendars and contacts that sync to phones.

We built and run the whole stack: the mail server, spam and virus filtering, SPF, DKIM and DMARC on every domain, attack blocking shared with our firewall, nightly snapshots and backups. Our last delivery test scored 10 out of 10.

The screens here show a demo mailbox with demo data.

  • Several domains on one mail server
  • SPF, DKIM and DMARC set to reject forged mail
  • Spam filter that learns, plus a virus scanner
  • Failed logins banned on the mail server and the firewall
  • Nightly snapshots and separate backups
