Hi,
When customers purchase on our site, we do get paid but the orders are never confirmed and we have to do it manually.
I went through all the posts about paypal notification problem, and your paypal issue page but I still have questions. 
See my screenshot attached.
1/ Should "Enable validation mode" be activated?
2/ I have disable "send details of the order" to prevent 1 cent problems. Is it correct?
3/ Is there any settings I am missing?
4/ In paypal, Where do you check the automatic validation activation? could you detail?

I have look but either it ask for IPN, return URL, ... I don't want to screw up everything. (screenshots)
I know you're not working for paypal but your help would be appreciated.
Phil.
