Spam Filters

today i was asked to look at spam filters http://www.spamihilator.com/ & http://www.spamweed.com/ i compared the both and seen what 1 of the 2 offered the best in blocking unwanted spam spamihilator was free but only offered a few scanning tools where as spamweed had a free trial with the option to buy with more scanning tools and spam blockers.
