[exim] Exim doesn't save mails to files anymore

Hi all,

i'm a recent exim users. I've modified the config files so that it passes
the mail through my php script on reception of the message.

But I don't figure out what i've done, the mails are not saved to files
anymore in /var/spool/exim4...
I don't know if it's a router that saves mails to files or anything else.

Please find attached my exim conf files.

Could you help me please?

Thanks
