[Exim] exiscan logging

Hi All,

I'm running exim-4.10 with exiscan-4.10-15. It's working fine, it's just that
all the message headers are being logged in exim_reject along with the reject
line. Is this standard? Does anyone know how I can turn it off. There's no
mention of it in the exiscan docs AFAICS.

Cheers
Rich
