You could start with $subject =~ /Viagra/i; which will catch all subjects which contain the word, in a case-insensitive way. However, 99% of Viagra ads now coming through have some form of obfuscation, including but not limited to: [EMAIL PROTECTED] V|agra Vi�gra V.I.A.G.R.A. Vi agra And so on. Use Spamassassin, auto whitelisting, greylisting, Vipul's Razor, DCC, and bayesian filtering and you'll kill 99.9% of them. Filter only by subject and you'll get less than 2% if you're lucky. Then try the same with Cialis and all of the other interesting strings, and see if your filter can do all of its checks before Sendmail times it out...
