[Exim] problems with debian

Hi, I had to recompile with debian the exim. So I downloaded the source
code for exim 3.35 and now it gives this error in the msglog. It doesn't
work with my old configuration that was working before. I had to change it
so MYSQL was installed with it.

here's the error.
