I have a exim setup that is a redundant MX.  The server accepts mail for 
a list of domains and holds the mail until it can deliver it to the 
primary server.  The problem i'm having is that this server gets a ton 
of spam because it's accepting mail for any recipient and then hammers 
the primary server.  I modified my check_recipient acl so that it has 
the following

   accept  domains = +relay_domains
   local_parts = lsearch;/etc/relaydomains/$domain
   verify = recipient


Before it only had

   accept  domains = +relay_domains

This works great as long as i keep /etc/relaydomains/$domain updates but 
the problem comes with some domains that have catchall type aliases.  On 
the primary server the aliases file has a *: catch...@domain entry.  
With the modifications above if i add * to the /etc/relaydomains/$domain 
it does not accept mail for all recipients.

Looking for ideas about what i need to do, thanks!
