Two decades of saying no to the right mail.
Spamjadoo is the anti-spam product of Data Xgen Technologies Pvt Ltd (DXTPL). It began as an answer to a simple observation: the cheapest spam to handle is the spam you never accept.
What we build
A mail gateway that makes its decisions during the SMTP conversation rather than after it. Every connection is judged on facts available at the handshake: where it comes from, what it claims to be, who it is sending as, and who it wants to reach. Most unwanted mail is refused there. The remainder gets the antivirus, Bayesian and DMARC treatment that every gateway offers, on a fraction of the volume.
Who runs it
ISPs and hosting providers who deploy it as the primary MX for thousands of tenant domains. Enterprises who put it in front of Exchange or Google Workspace. Public-sector bodies in India who need mail to stay inside the country and to work in Indian scripts.
Spamjadoo is also the antispam engine that powers XgenPlus, DXTPL's Enterprise email server. And it is the official antispam MX gateway for the Government of Rajasthan, a deployment won through competitive bidding.
Where we are going
Email address internationalisation is the part of anti-spam software that still gets it wrong most often. Spamjadoo's EAI work, and DXTPL's wider work on local-language email, is where much of our engineering goes today.
