Re:Spews is NOT the right way to filter e-mail.

Spews randomly blocked a consulting company's netblock I worked for part-time simply because that our block was next to a "known spammer's" block. When they politely asked to be removed and pointed out that according to their own evidence file that their netblock had nothing to with spam, they were met with very hostile responses and told to essentially ditch their teleco provider because they'd never unlist anyone. They admitted that they simply block IPs in a form of "collateral damage" because they feel like it to hurt legitimate businesses so they flee their network provider. Someone mentions C&W addresses, same thing if you're getting service from Qwest. Their website makes them come off as the noble crusaders against spam, but in reality what they do is just mean-spirited, unethical and just plain wrong.

Don't use SPEWS!

See the newsgroup news.admin.net-abuse.email to see just how the spews people treat those who politely ask for erroneous entried to be removed and PROVE they have nothing to do with spammers.
