DPXchange
The licence service and installer for DPXchange, the Exchange-compatible mail server from Dual Path.
Install
On a fresh Debian 12 server (2 GB of memory or more, 4 GB recommended), run:
curl -fsSL https://dpxchange-licensing.dp.dpai.sh/install | sudo bash -s -- --host mail.yourcompany.com
The installer sets up the mail platform and DPXchange, then prints the address of the setup wizard and a one-time setup code. The wizard walks you through activation, your mail domain, DNS (automatically, if your DNS is at Cloudflare), the certificate, outgoing mail and your first mailboxes. An AI assistant such as Claude or ChatGPT can connect to the wizard and help.
You need
- An activation key from Dual Path.
- A server name you control, such as mail.yourcompany.com, and access to your domain's DNS.
- Inbound ports 25, 80, 443, 587, 993 open. If your provider blocks outgoing port 25, the wizard sets up a relay.
Every release is signed by Dual Path, and the installer refuses one whose signature does not check out.
