------- Additional Comments From [EMAIL PROTECTED] 2004-03-12 09:07 ------- With the patch above obfuscation is not suspected if the run of non-whitespace after the tag does not consist of an alphabetic character. I've since gotten legitimate E-mail in which the run of text before the tag consists of only non-whitespace, non-alphabetic characters (a single open parenthesis). With the patch below obfuscation will be suspected only if the runs both before and after the tag contain at least one alphabetic character. This (<xx>an let some true 0<yy>bfuscation through, but I'm guessing that the limited number remaining obfuscation opportunities would increase the effectiveness of the keyword scanners and Bayesian classifiers that obfuscation is trying to evade. As it stands (see below) the 0-10% obfuscation rule can't be scored very highly, so the change should help. (So would a 0-5 rule.) >From http://www.pathname.com/~corpus/DETAILS.1day (12 March 2004) OVERALL% SPAM% HAM% S/O RANK SCORE NAME 14.467 18.3443 3.3682 0.845 0.59 1.00 HTML_OBFUSCATE_00_10 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
