Can you find out what caused the ISP to suddenly block her out going mail? Did she send something that triggered their system to shut her down? Before any changes are made, I would have her back up EVERY subdirectory and file name associated with her current mail system (twice to be safe).

To make sure I understand this, Cloudmark runs on her normal ISP watching her email or is it her ISP also? If it is running on top, who is her ISP and they should be the ones to change her IP address. I looked at Windows Live Mail and it said it worked back in the XP and earlier days and is now discontinued! Seems to me she is trying to get by with outdated software and should upgrade to the latest versions of Windows and go with Outlook and dump the Cloudmark?
