CAUTION : We strongly advise against downloading and copying mailContentHandler.js to your appropriate Windows system directory. Qualcomm typically does not release Eudora OSE JS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing mailContentHandler.js and all other JS files for Eudora OSE. An incorrectly installed JS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
