LB Mail Sitter

LB Mail Sitter 2 reveals a powerful and specialized tool designed to combat some of the most common and costly human errors in corporate email communication: sending emails to the wrong recipient and leaking confidential information. Positioned as an add-in for Microsoft Outlook, its core function is to intercede before a message is sent, forcing a critical confirmation screen that displays recipients and attachments. This double-check mechanism is the primary safeguard, but the software extends far beyond a simple prompt. In its newest version, it has evolved to become a direct countermeasure against PPAP (Password-protected files in email with password sent in a separate email), with the ability to prohibit attachments that are already encrypted ZIP files and to offer the new "File Lock" encryption format, which supports the robust AES256 standard. Its feature set is built for a controlled corporate environment, providing functions like keyword and recipient warnings or outright prohibitions, automatic CC/BCC additions, and the ability to add predefined phrases to messages.
