[Exim] EXIM input and msglog

Hi people,

I've been using Exim for several time now,
and I have the following problem, exim keeps
writing files to msglog and input directories
and it fills up my disk, about 10GB of files in
less than a week, how can I tell exim, no to write
msglog files and to erase old input files, or
if there's another solution better?

Saludos

Muchas Gracias
