This article explores why the mailto protocol in HTML cannot directly send attachments, primarily due to security concerns. By analyzing the design limitations of the mailto protocol, it explains why attempts to attach local or intranet files via mailto links fail in email clients like Outlook 2010. As an alternative, the article proposes a server-side upload solution combined with mailto: users select a file to upload to a server, the server returns a random filename, and then a mailto link is constructed with the file URL in the message body. This approach avoids security vulnerabilities while achieving attachment-like functionality.
