Where's the code that fills $mailContents?

Does it perhaps look like this:

my $file = 'mailmessage';
open( my $fh, $file ) or die "couldn't read file - $!";
my $mailContents = <$fh>;
close( $fh );

... or similar?

You might instead want:

my $file = 'mailmessage';
open( my $fh, $file ) or die "couldn't read file - $!";
my $mailContents;
{
  local $/;
  $mailContents = <$fh>;
}
close( $fh );
