file extension CNM - Pegasus Mail new mail message
File extension CNM description:
This file extension represents an actual new mail message. When new mail arrives for a user, it will have this suffix (this is compatible with direct server delivery, Mercury and Charon). The filename is unique, and can be considered as its message id. The actual name generally begins with a Y to indicate a normally delivered new mail message (local or by Mercury), or P to indicate a POP3-delivered message.
If the general preference to keep new messages in the new-mail folder is set, in the versions before the 3.0, the first character of the message id will become a ! when the message is read but not moved. In the 3.0 version the file is no longer renamed.
The structure of the New Mail folder is unique in that individual messages are stored as individual files whereas other folders have all their messages stored in a .PMM file with a corresponding index file with a .PMI extension - one file pair for each folder.

Aid4Mail™
Aid4Mail™ is a sophisticated but easy-to-use tool that can migrate email to a different mail client, export it for viewing through Internet Explorer®, Microsoft Excel®, and most databases, and archive it to save space or for regulatory compliance. It can merge mail into a single mailbox file, or export it as individual message or text files, and can extract attachments, embedded contents, and email addresses.
Aid4Mail supports over 30 email clients and mailbox formats including Outlook 2007, Windows Mail, and Windows Live Mail (see the Specifications page for a full list). Unlike the native import and export features of most email applications, Aid4Mail migrates mail without losing formatting, sender/recipient information, attachments, embedded contents, or message status (see the Conversion Quality page for examples). This capability is crucial to large-scale migrations. Aid4Mail can process mail folders and files even when they are disconnected from their email client, including those stored on a CD or DVD. It can filter mail by date range, header content, and in the Forensic, Enterprise, and Console versions, by message body content.
