Blocklists: There's a bunch out there. The ones that come to mind are:
- DNS Realtime Blackhole list
- IBM DNS Blacklist
- Spamhaus ZEN
Frequency: It would be nice to choose between daily or weekly, with maybe an ad-hoc option.
IP/Domain: Some block based on IP some on Domain. We have multiple email domains with only 1 or 2 servers. Ideal case would be both, but, in a pinch I'd have to go with Domain.
This is sweet! Any idea on when????
Thanks a bunch,
