If you want to use asterisk symbols as part of a rule, you must enclose all occurrences within double-quotes. For example:

"www.evil.com/*./phish.cgi?param=foo*"

The double-quotes tell Spamphibian Gateway to treat the asterisk as a literal character, not a wild-card character. Similarly, if you would like to use plus symbols in a rule, they must also be enclosed within double-quotes as in:

"www.evil.com/test.cgi?foo+bar"
