A New Generation of Mail Transfer Agent

Whereas optimizing allocated resources is becoming a growing challenge, computer attacks remain a constant issue. Over 300 billion emails are sent and received in the world every day. Billions of duplicated attachments are processed, analyzed and delivered, contributing to the increase of greenhouse gas emissions.
To meet this challenge, viridIT is developing a new technology of email gateways, called vSMTP.


Customizable security policies

It is modular and highly customizable. Users can generate complex routing and filtering scenarios through a simple and intuitive scripting language. Adding or modifying subsystems is facilitated by the internal design of the software. An API is available allowing easy integration into existing security elements. Several native plug-ins are already available.

It has a complete filtering system. In addition to the standard analysis of the SMTP envelope, vSMTP adds the possibility of interacting on the fly on the content of messages (MIME). It is possible to filter, modify, encrypt, etc. any part of an email.

It is developed in RUST. Compared to solutions developed in C / C ++, RUST guarantees the absence of segmentation errors and race conditions. It is the latest generation language best suited to system programming, network services and embedded systems.The network code has been designed with performance and load resistance as the main objectives.

Its development goes through a full cycle of testing. Static and dynamic tests allow more comprehensive coverage of safety tests, one covering faults of the other and vice versa (static view and runtime view). Likewise, random data tests (fuzzing) and load resistance tests are performed.


vSMTP, The next mail transfer agent

It is faster and greener. Developed in RUST, the vSMTP engine is a fast and secured SMTP router including a powerful e-mail filtering system.
It is a more efficient, more secure and more ergonomic product than the competition. 

vSMTP is up to 10 times faster than its competitors and significantly reduces the need for IT resources.
