Today I posted the SpamBouncer's internal domains and iP lists on the SpamBouncer web site as separate data files. These lists are in plain text format in SpamBouncer 2.1, rather than embedded in Procmail code. The domains are listed a single domain to a line. The IPs are in CIDR format.

Feel free to make what use of the data you will. <G>
