Registering mail hosts

Although I first started reporting spam to Spamcop at least as far back 
as early 2002 I stopped reporting several years ago; precisely why I 
cannot recall.

Having decided to give it a go again I am having a slight difficulty 
deciding how to respond to the mail hosts configuration set of pages. I 
understand the general principal of configuring the final receiving host 
first BUT this appears to not quite dovetail with my particular set-up. 
I will try and explain.

The final receiving 'mail host', which I will call 'domain Z extension', 
is a pop3 server running on my PC, i.e. I have configured it to use 
domain Z in the receiving header it generates. It collects mail from all 
my other hosts. Domain Z is also my legacy domain and Broadband provider 
BUT I do not collect legacy email directly from its servers. Instead, I 
have domain A hosted at a different service provider which automatically 
collects mail from domain Z and drops it in a domain A pop3 mailbox. The 
same provider also hosts half a dozen or so further domains that I 
manage, e.g. domains B,C,D,E etc and the final destination of all mail 
for those domains and of course Domain A is my local pop3 server, domain 
Z extension.

My registered Spamcop address is in Domain A, not Domain Z. Domain Z 
mail is only collected at hourly intervals and is also filtered through 
Brightmail at Domain Z. Domain A mail is also filtered through 
SpamAssassin but I have total control over that so I prefer my Spamcop 
reporting address to be under that domain.

The problem is that the first hosting domain configuration page (which 
has to be for the last receiving host) appears to be tied into the 
spamcop reporting address which is NOT the last receiving host in the 
chain.

Advice anyone?

Thanks,

Chris
