Tailored to suit you

Fully scriptable, customizable and extensible, but lean and compact at the same time. A lack of flexibility in the MTA can lead to compromises and complexity, resulting in high maintenance costs and risks. The Halon MTA can be tailored to your specific needs with virtually unlimited customization.
