Services Architecture

Axigen Documentation

Axigen is an integrated service SMTP, IMAP, POP, secured SSL/TLS, WebMail and list server, integrating advanced technologies and messaging services.

Services and modules

The Axigen messaging solution is built on an Internet-based mail server that provides messaging services over the Internet via connections using a Transmission Control Protocol/Internet Protocol (TCP/IP) network. Axigen sends mail messages using the Simple Mail Transfer Protocol (SMTP). The messages can be retrieved using the Post Office Protocol version 3 (POP3), the Internet Message Access Protocol (IMAP), WebMail or using your mobile device to access the Mobile WebMail, a lite version of the WebMail interface or using ActiveSync technology to keep your messages, tasks and contacts synchronized with ActiveSync clients. Axigen Mail Storage integrates a proprietary technology that allows storing messages in a special directory structure, guaranteeing an effective, fast mail flow and optimizing space-saving.

Architecture Features

Axigen incorporates a multi-threaded engine, which can break server activity into multiple parallel processing threads. This enables you to allocate a certain number of processing threads to specific modules (SMTP incoming / SMTP outgoing / WebMail / IMAP etc.) Running services can be configured at service, domain and account level.

Most Axigen services (SMTP Incoming, SMTP Outgoing, POP, IMAP, WebMail) make use of configurable listeners to define rules for accepting or denying connections.

Administration Tools

The administration tools enable both centralized configuration (WebAdmin and Command Line Interface) and manual configuration (configuration file).

For each service described in the Architecture chapter, configuration options are available in each of these tools (WebAdmin, CLI and the configuration file, axigen.cfg).


Axigen incorporates an advanced filtering system and other innovative security tools (AntiVirus, AntiSpam, AntiSpoofing - SPF Authentication, SSL/TLS authentication etc.).

Highly configurable logging and reporting services are also available, and a Backup service allowing you to securely backup and restore your domain and user configuration.
