This problem also effects Thunderbird (tested) and im guessing
Netscape's Mail client (untested) which it really can't do much except
cause Thunderbird/Netscape to crash without javascript.

Include the linked source in an email for your testing.

Only the newest 7.x version 7.2 has an internal Mail client. Version 8.0.3.3 is browser-only version. Version 7.2 has unpatched, confirmed vulnerabilities due to older codebase like we know. Version 8 was released to fix them. Your report will never reach Netscape due to non-working security [at] netscape.org (please read instructions to contact the vendor below).
