Meet Environment Social and Governance corporate goals by reducing resources needs by at least 50% on mail and IT security.
vSMTP can act as a pure MTA, as a secured front-end on the Internet, or even as a mass email sender.
vSMTP is mainly developed under the GPL license. Source code is available for benchmarking and testing.
Users can generate complex routing, filtering, and sending scenarios through a simple and intuitive advanced scripting language.
It is developed in Rust, guaranteeing the absence of segmentation errors and race conditions.
Its modular design makes it easy to integrate new components while following a full cycle of static and dynamic tests.
Get all the benefits of a commercial grade mass mailer MTA while meeting corporate environmental goals… at the price of an opensource software.
vSMTP for e-commerce supports DKIM, SPF, DMARC and ARC. TLS and DANE protocols are supported for secured transactions.
Optimize your sending speed or warn up IPs by tuning all major settings per target provider such as throttling, connections, IP addresses, etc.
Integrate vSMTP into any infrastructure thanks to SMTP, HTTP, and JSON injectors. Use any vSMTP plug-in to connect external services such as databases, security components, etc.
Like the vSMTP core, e-commerce addons are developed mainly in Rust, guaranteeing the robustness of the solution.
View real-time data through the vSMTP dashboard and export data to your infrastructure using logs, JSON, or MQ API.
Optimize your MTA infrastructure as vSMTP is up to ten time faster than competitors. Reduce significantly your security components such as antivirus and antispam with the unique vBOOST technology.
Counter email tampering and comply with the newest RFCs like ARC. Enhance security transaction using TLS and DANE protocols. Access to existing security components like DNSBL, antivirus, etc. through dedicated plug-ins.
View real-time data through the vSMTP dashboard and export data to your infrastructure using logs, JSON, or MQ API.
Manage multi-domain infrastructures with vSL, the vSMTP scripting language. Connect external services such as databases, security components, etc. using plug and play connectors. Develop your own native plug-ins.
Make your customers aware of the environmental impacts of emails by using vGREEN technology.
Counter mass mailing traffic and optimize your SMTP traffic speed by adjusting all major settings per target receiver or provider such as throttling, connections, IP addresses, etc.
