PowerMTA is designed for senders moving well beyond what a single small server handles comfortably: per-domain throttling, detailed bounce classification, and often multiple IPs to spread reputation across sending pools. That workload benefits from real CPU headroom and fast storage for its logging and accounting database.
Our Advanced and Pro plans provide that headroom, and additional dedicated IPv4 addresses can be added on request for senders running IP pools or warming up new addresses gradually.
