MailAccess
A self-hostable OSINT tool for investigating email addresses across breach databases, social networks, DNS records and the open web, producing an exposure score and structured findings.
MailAccess is a self-hostable OSINT platform for investigating email addresses. It fans an address out across breach databases, social networks, DNS records and the open web, then returns a unified exposure score and structured findings that can be exported or piped into Maltego. It is built for security researchers, OSINT analysts and penetration testers operating under authorization.
Its identity graph cross-correlates accounts, usernames, names, avatars, breach data and profile links across a corpus of more than five thousand platform definitions, while a name consensus engine turns independent name signals into confirmed, probable, possible or unknown bands. A defender's brief and a separate credential risk score summarize findings with prioritized next actions.
Domain email harvesting discovers organization addresses across sources such as Common Crawl, GitHub, certificate transparency logs and key servers, and a company email pattern feature turns a name and employer domain into a graded likely address using an offline pattern index. It installs as a Python package and can run as a one-off command or a persistent server.
