About:
Exim is a highly configurable Mail Transfer Agent (MTA) used for routing and delivering email on Unix-like systems. It serves as a drop-in replacement for Sendmail, offering advanced features for spam filtering, virus scanning, and flexible routing logic. Its primary value proposition is robust performance and deep configurability for high-volume mail environments.

Key Features:

Highly configurable routing and delivery logic
Built-in support for SMTP, LMTP, and pipe transports
Extensive content scanning and filtering capabilities
Compatibility with Sendmail configuration and command-line options

Use Cases:

Primary mail exchanger for enterprise or ISP mail servers
Gateway or relay host for internal networks
Custom mail routing and filtering pipeline

Alternatives:

Postfix – Postfix focuses on security and ease of configuration, while Exim offers deeper customization at the cost of complexity.
Sendmail – Sendmail is the historical standard; Exim is often preferred for modern use cases due to better performance and security defaults.
