Javascript tags showing in ticket text

RT 4.0.5 with all dependencies installed.

Some tickets are created by users emailing us from Outlook. In some of
these tickets, I see this stuff:

Company Name<javascript:sortColumn(‘2’,‘desc’)>


Since when<javascript:sortColumn(‘4’,‘desc’)>

It’s displayed verbatim in the ticket body. I’m sure this is not
displayed like that by Outlook.

Any way to get rid of that javascript tag noise?
