I/O Completion Technology

Instead of traditional multiple-threadings technology, I/O completion is used in EmailArchitect Email Server. It delivers the highest performance on Windows Platform as only one thread can handle thousands of concurrent socket connection. Low CPU and memory usage contributes to the maximum performance on a single server.

Access Control

Relay restriction and ESMTP user authentication are good features to prevent spam from spreading out from anonymous user. In Connection Control or Relay Restriction, the IP addresses can be represented by wildcard(*,?) or CIDR syntax to describe the IP addresses range accurately.
