You can search the entire database for Domains or email subjects. Some items have a further description which is displayed by clicking on the respective Domain Name. Detail for each Domain includes:
individual emails sent on behalf of this Domain
a link to other emails with the exact same subject
which Domain(s) this Domain Administrates
which Domain(s) this Domain Hosts
which Domain is this Domain's Administrator
which Domain(s) is this Domain's Host
If you spend some time with the List you'll find there are patterns (email subject, Domain Names, who hosts whom, etc.) and this may assist you in figuring out how to anticipate future spam for your own filters.
