Re: [anti-spam-wg@localhost] I wrote a spam filter in Perl

["pna.lists" <]

1) English-like syntax rules file is cool, but is it flexible enough? Does
it still filter spam when the spammers write V1arga instead of Viagra?

2) You may want to start doing pilot projects with (fre)email providers,
hosting companies and the ASP's

3) Have you measure the false positive and false negative results?

4) There *are* some Perl compilers available - it depends on the platform
you are using / targeting

5) You may want to try some Perl obfuscators
