AdminSystem Software Limited is your ultimate destination for professional-grade email components and email server solutions. We offer a wide range of competitively priced, easy-to-use, and high-performance products designed specifically for developers and administrators. Our email components include SMTP, POP3, and IMAP4 components, which allow you to easily send and retrieve emails in various programming languages such as C#, VB, C++, and Delphi.

With support for SSL, TLS, embedded images, EWS, and OAuth, you can ensure secure and efficient email communication. In addition, we provide DKIM for Exchange Server and Windows Email Server, allowing you to add DomainKeys/DKIM signatures to outgoing emails, preventing them from being flagged as spam or junk mail. Our S/MIME and Disclaimer solutions for Exchange Server and Windows Email Server enable you to add HTML disclaimers or signatures with embedded images and digital signatures to outgoing emails, making them more professional and secure.

For Exchange Server users, we offer Sender Based Routing, which helps re-route email messages based on sender, group, recipient, and subject, as well as Opportunistic TLS Router, which redirects email messages to a plain TCP server when TLS is not supported by the recipient server. Additionally, our EA Oauth Service for Office 365 makes it easy for legacy email applications to connect to Office 365 using OAuth 2. 0, allowing seamless integration without the need for code changes.
