Is there any reason why it wouldn't be a good idea to make the header check in sub perlscan_scanner case insensative? e.g. change
 
if ($headers{$type} =~ /^$var$/)
 
to
 
if ($headers{$type} =~ /^$var$/i)
 
It would definitely save some typing and cut down on the complexity of quarantine-attachments.txt when adding rules to block messages with undesirable content (i.e. 4 letter words, pornographic terms, etc.) in the subject of the message.
 
Thanks,
 
J.T.
