ideas on why this rule isn't working?

[Johnson, S]

I have to admit… Some people are actually trying to help me keep bad material out of our school district.  They are attaching a “sexually-explicit: text text text” in the subject line.  So I thought that I’d write a rule to catch that and re-route the mail to the blackhole.  Any ideas on why this isn’t working?  Thanks!   header ZXS_SEXUALLY_EXPLICIT  Subject =~ /\bsexually-explicit/i describe ZXS_SEXUALLY_EXPLICIT bad...bad...bad... score ZXS_SEXUALLY_EXPLICIT 10 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Confidentiality Notice If the information in this electronic communication relates to an individual pupil, it is a confidential pupil record under Minnesota Law and may not be reviewed, distributed, or copied by any person other than the individual(s) to whom it is addressed.
