I use the following banlist, works pretty well for me, for MAIL FROM stage:

  deny
    message = Banned TLD
    sender_domains =
^(?i).*\\.(bid|store|club|top|xyz|pro|date|faith|stream|host|loan|download|click|link|science|design|gdn|men|win|party|webcam|rocks|email|life|ninja|online|racing|review|site|trade|vividal|website|works|work|cricket|help|camera|computer|space|uno|tech|news|space|guru|berlin|photography|global|today|solutions|media|world|university)\$


And also for MIME From, for data stage:

 deny
    message = Banned TLD in MIME From ($h_from:)
    condition = ${if match
{$h_from:}{^(?i).*\\.(bid|store|club|top|xyz|pro|date|faith|stream|host|loan|download|click|link|science|design|gdn|men|win|party|webcam|rocks|email|life|ninja|online|racing|review|site|trade|vividal|website|works|work|cricket|help|camera|computer|space|uno|tech|news|space|guru|berlin|photography|global|today|solutions|media|world|university)>\$}{yes}{no}}


Combined with some subject bans to catch like Viagra and such, it filters
like 90% of the spam. I can see in the logs lots of spam that gets rejected.
