That's a completely valid approach, and I am a big fan of pre-emptive first strike (only as applied to potentially evil email). However, the vast majority of those TLDs will never "go rogue", so I prefer to block on actual abuse (Jason's approach), or likelihood of abuse, specifically, very low cost. Jason appears to have much higher volume than I do, so he'd be a good source of data for me and others. IDIC... or to each his/her own preferred approach. :) - "Chip"
