Is Spamihilator “open source”?
No, Spamihilator is not open source. Even though the program is free to everyone, the programmer doesn’t give away the source code anymore. Spamihilator was open source until an anti-spam company copied and sold the program. Please see this topic for details (it’s in German): http://www.spamihilator.com/forum/viewtopic.php?
