1 A FULL-STACK SMTP PLATFORM Open & Scriptable, Targeted Specifically at Large-Scale Infrastructures

2 The Halon SMTP Platform is software for distribution, providing a full stack consolidated approach to everything you need in front of your storage. Using a flexible and scriptable engine, designed to be run as part of a fault tolerant and linearly scalable cluster, the Halon Platform integrates with surrounding modules and infrastructures seamlessly using SOAP/REST APIs. Key functionality includes routing, anti-spam, rate limits, signing, content filtering and multiple outbound deliverability mechanisms. The Halon SMTP Platform reduces complexity and eliminates the burden of maintaining many separate systems, making management more simple and effective. The Halon SMTP Platform enables demanding organizations like hosting providers and MSPs to implement ideal solutions for their specific needs, making Halon the perfect fit. in- & outbound SMTP REWRITE SCRIPTING SIGNING RATE LIMITS REST API databases ctrl panel ANTISPAM ROUTING ETC... integration LMTP or SMTP storage servers

Halon is the open, scriptable alternative to building and maintaining a home-brew system. Its -centric scripting language enables you to rapidly architect the system that you need, without compromises. There are official plugins for cpanel, WHMCS and Parallels that you can build upon.

4 Successfully delivering is important for webhosts, ESP s and VPS providers. The scripting language lets you design and tailor the logic to handle compromised accounts and abusive users; in order to avoid blacklisting without bothering legitimate users. You could for example combine rate limit with anti-spam, delivery failure rate and queue length for a specific sender, source-hash sender domains, send suspicious out through a separate bulk IP, and control outbound connection concurrency. It can even function as a fully transparent proxy. The scriptable reporting provides comprehensive delivery reporting and analysis. Finally, thanks to the DKIM (based on our open-source library) module s tight integration it provides signing at blazing speeds. Update your entire delivery platform, architected using our high-level scripting language with one click, instead of having to update many small software components in several different systems. By completely overwriting the system partition from an update partition, updates are quick, reliable and there is no need to worry about regressions or broken dependences. avoid BLACKLISTING

5 Halon s integrated and scriptable approach to anti-spam, signing and verification, policies and inspection enables enterprise-grade security at hosting-grade performance and at a price that fits your business model. Transaction safety (in-transit reject) and anti-spam from leading vendors make your customers forget about spam, without worrying about losing genuine .

6 Halon s -centric scripting language helps service providers to do rapid implementation of new technologies in a way that fits them, to keep up with the competition. Examples we have seen are DKIM signing with keys delivered from a control panel using a REST API, custom SRS, dynamic routing and tailored outbound policies for maximum deliverability. The sandbox, REPL interpreter and revision management make deployments safe and efficient.

7 ADD-ON SOFTWARE logging server: An open source, customizable end-user and logging web interface, to be used with the Halon SMTP Platform. In addition to history and logs, it contains queue management, quarantines, archiving, statistics, and much more. It s useful for administrators as well, in order to store long term for compliance and search history logs. halonctl: An extensible command line utility for managing Halon nodes and clusters written in Python and freely available as a pip package. Useful for tasks such as updating and configuring nodes, even in multiple clusters and can be extended with custom functionality.
