disable the Flash Player ActiveX control in Internet Explorer 6 and newer versions on all web sites.

Alternative NoFlash implementation

On versions of Windows® that ship without Flash Player, an (empty) file %SystemRoot%\System32\Macromed blocks the installation of its ActiveX control and the NPAPI as well as the PPAPI browser plugins instead of only disabling the ActiveX control.

Notes: I dislike HTML (and even weirder formats too) in email, I prefer to receive plain text.
I also expect to see a full (real) name as sender, not a nickname!
Emails in weird formats and without a proper sender name are likely to be discarded.
I abhor top posts and expect inline quotes in replies.
