If there are discernable patterns, can you share the patterns and/or rules to catch them?
simple checks: - they contain a url in a known free hoster - most have helo != rdns - many have rdns = unknown - many have rdns = looks dynamic
more importantly, there are things related to the data. but I don't wanna help spammers.
