[exim] Blacklisting Recipients

Hey folks,

We have been hit with a lot of phishing attempts lately, and while our
users are pretty good about it, I'd like to be able to implement a
recipient blacklist on the server.

What I have so far is:

================================
## In the acl_check_rcpt section, below "accept local_parts =
postmaster : abuse"...

deny message = The recipient ($local_part@$domain) is suspected of phising....
acl = acl_black_local

================================
## Then down below, right before the Routers section....

acl_blacklist_local:
deny hosts = lsearch;/usr/local/etc/exim.host_blacklist
deny senders = lsearch;/usr/local/etc/exim.sender_blacklist
deny recipients = lsearch;/usr/local/etc/exim.recipient_blacklist

================================

In the /usr/local/etc/exim.recipient_blacklist file, I just have email
addresses.

What am I missing?

Thanks!
