Thanks for the tip Jez but I'd still like to know what the @@lsearch* all
means.

One way you could block mail from a number of domains is to define a
domainlist called 'blacklist_domains' at the top of the exim configure
file:
domainlist blacklist_domains = /usr/local/exim/blacklist.txt
and then reject mail from those domains near the top of your RCPT ACL:
deny sender_domains = blacklist_domains
I'm not sure how you can block mail from just a selection of addresses
on a given domain which is perhaps what you were after if you're using
lsearch.
