In addition to the previous suggestions, you can eliminate the loop over @configLineItems by compiling a regular expression with qr like this:

my $regex = join '|', map {quotemeta} @configLineItems;
$regex = qr/$regex/;

(If @configLineItems contains regular expressions, then drop the "map {quotemeta}".)

This is something you can do when you read the configuration file before the loop over the input file, storing $regex for use during the main loop over the input. You can then use it like so: if ($Line[6] =~ $storedRegex)

As was said earlier, as much as we like to help, this isn't a code writing service - please try to implement these suggestions and if you need help doing so please don't hesitate to ask.
