Looking at the code snippets above, you will notice you are converting a single whitespace into a 'dot' (.) When you have multiple spaces you will end up with nulls in the middle of your @subject_array and your source file will need to have a dot per every whitespace for the exact match to work. tabs I dont think are allowed in a subject, but hey, since when have spamm,ers followed the rfc? a tab would not be interpreted at all by your code. I am not sure if either of the above would break anything as perl is pretty forgiving of these things. However, you might consider substituting on whitespace like so: $lc_subject =~ s/\s/./g; which will squish multiple spaces down to a single dot, this might make your source file smaller as well and would handle tabs as well.
