20 years ago, sending mail was a simple SMTP handshake. Today, OAuth2 tokens, Microsoft Graph APIs, and vendor-specific authentication break legacy hardware and medical workflows. MailDelegator bridges the gap.
Who needs a dedicated app just to send outbound email? Anyone trying to keep legacy infrastructure running in a modern security paradigm.
Google, Microsoft 365, and Yahoo have effectively deprecated basic SMTP authentication. Modern mail delivery requires handling:
Modernization doesn't happen overnight. Organizations are caught in the transition:
MailDelegator strictly **does not receive mail**. By stripping out listening capabilities, the attack surface drops to zero. Ideal for strict HIPAA and medical environments.
Under the hood, MailDelegator encapsulates Microsoft, Google, and Yahoo OAuth2 identity protocols and APIs. Your systems trigger the dispatch; MailDelegator does the heavy authentication lifting.
Built with **C# and Avalonia UI**, MailDelegator runs natively on Windows, Linux, and macOS without compromising performance or visual consistency across OS environments.
