Ahh okay, I was unsure what happens when exim calls in and scans the

Okay this I can understand, so I should leave exim calling dcc-proc and

I never realised that the checksums went this high. I may wait till I
get a DSL connection and then be in a possible to help out with a server
to help split the load :)
