Shouldn't be a problem. You would use the sender_reject_recipients
main configuration parameter. A line of the form:

sender_reject_recipients = cdb;/etc/exim/spamlist.cdb : \
                           *@cdb;/etc/exim/spamlist.cdb


will be the rough equivalent of the above. Don't forget to set the
recipients_reject_except main configuration parameter to ensure mail
to postmaster gets through. I've not tested the above as we've now
switched to exim4.

>but believe me, you will not regret an upgrade to exim4.


Agreed, exim4 ACLs are *much* more flexible and well worth any
upheaval in the transition. I moved our stuff across by setting
up a test machine and thoroughly testing that before we went live.
Thia was well worth doing.
