If your problem is, that you will read the emails without Pegasus Mail on your system, than you can link .CNR and .CNB to any software, that is able to read EML-Files.
For reasons of security we did not link new mail files (.CNM). It is however just as possible.
We use this feature to search by help of Windows explorer in Pegasus Mail systemwide folders and noticeboards.
For Outlook Express or Windows Mail clients it is necesseary to add some registry keys in the classes root. It is tested with Windows 2000 up to Windows 7 x64 (W7 must patched to Vista WinMail).
