Almost by mistake I found a bug i the x-mailer plug in.
If the X-Mailer-header field contains html-characters, such as < and >.
They are not displayed in a proper manner. This is first of all a
graphical bug but I guess maybe one could use this to execute some evil
I've made a quick fix using the htmlentities function but this function
only use ISO-8859-1 charset so I guess a better fix should be made.
!!! This fix is untested but you probably get the general idea. !!!
