The 90% figure is more down to our lack of bravado when configuring this 
product which is still very new to us. When looking at what actually gets 
through to the mailboxes (ie not counting those in the quarantine area) it's 
much more like the 98% you cite above  :-)

However, the point is that the vast majority of mail gets through and three 
(known to be ham) mails have got screwed up. I will build another box using 
the packages you describe and see how we get on. It should quickly become 
clear whether the introduction of DCC, Razor, SURBL and rules_du_jour 
resolve this issue, I'll keep you posted.

I appreciate your feedback very much and love the product despite this small 
issue. I am determined to get this working. Thanks Julian.
