#This script randomly extracts SPAM subject lines from your spam folder (I have a procmail rule that
#moves spam assasin taged mail to this folder) and can display them. 
#
#I use it with and built it based on the Courier IMAP implementation of the Maildir format for
#storing mail. Which means it probably wont work with mbox files 
#I have not tried it with other maildir implementations 
#
#I use it as a cgi with an SSI to include it on a web page
#
#You will need to insure that user your webserver runs as has read access to your SPAM folder
#
#I use system time for entropy which it is not, so its not really random but it serves the purpose
#
#The sed expressions strip the subject and duplicate subject which exists becuase of spam assasin
# 
#set SPAMDIR to the path to your "cur" folder in your spam directory 
#
#END COMMENTS
