I want to whitelist a large number of IP addresses; can I use wildcards?
Yes, as of spamdyke version 2.2.0. The whitelist and blacklist IP files will work with partial IP addresses to represent ranges. As of spamdyke version 2.4.0, whitelist and blacklist IP files can also contain IP addresses as dotted quad IP address followed by a netmask as a number of bits. Also, spamdyke supports dotted quad IP addresses followed by a netmask as a dotted quad. As of spamdyke version 3.0.0, whitelisted IP addresses can also be found by using a DNS realtime whitelist. This is like a DNS RBL that lists whitelisted IP addresses instead of blacklisted ones. For complete details, see the README page.
