Deploy a clean Linux OS (CentOS, Debian, or Ubuntu are most common).
Ensure you have a static public IP address with clean reputation. 2. DNS & Deliverability Records You must map out your DNS carefully to hit the inbox: rDNS (PTR): Map your IP back to your sending domain. SPF: Specify which IPs are allowed to send on your behalf. DKIM: Cryptographically sign your emails.
DMARC: Protect your domain from spoofing and direct inbox behavior. 3. Installation Commands For a typical RPM-based system (like CentOS): New Features for PMTA 5.0 - SparkPost
If you need PowerMTA for learning or testing, you can request a trial version from SparkPost (if still offered for legacy 5.0). Otherwise, their newer platform (Message Distribution Engine) may be the current product.
