Sendmail brand sendmail doesn't deliver in the background like
everything else.  This change should make RT return much more quickly,
which eliminates the fastcgi issue you're seeing.

Because the RT server is spending a long time actually trying to send
the email in its "foreground" and waiting until it's delivered before it 
returns. Other MTAs default to background delivery, so they return
quickly. The FastCGI server isn't seeing anything come back from the RT
server so it assumes it has hung and returns an error.
