Enterprise-grade control, protocol-level defense.

A gateway in front of Exchange, Microsoft 365 or Google Workspace that refuses most junk before it is accepted, and gives you one policy for the whole organisation.

What changes on day one

Your MX points at Spamjadoo. Directory harvest attempts against your domain stop, because unknown recipients are refused at RCPT TO against your directory. Mail from listed sources, forged senders and servers with no reverse DNS is refused with a reason. What reaches your mail platform is the mail that passed every check, and its own filters see a fraction of the volume.

Policy by group, not by server

Finance can require TLS from every counterparty and reject anything with an executable attachment. Recruitment can accept mail from anyone but route it through stricter content scanning. Executives can have JMail aliases for public-facing addresses. All from one console, applied per user or per directory group.

Compliance and residency

Hosted nodes in India, or on-premises inside your perimeter. Message logs record every check applied and every hop's encryption status. Message encryption at rest for regulated content. Archiving hooks to your existing store.

Works with what you have

Setup notes for Exchange, 365, Workspace and others are on the integrations page. The gateway relays to any SMTP destination and reads recipients from Active Directory, LDAP or an SMTP callout.
