Try splitting the data into lines.
my $subject = grep { /^Subject:/i } split /\n+/, $data;
You could also just use a regex:
my($subject) = $data =~ /^Subject: (.+)$/m;
That also captures the subject for you. Note that the parens around
$subject are required for a list context so that the m// returns the
string instead of the number of matches, and the m so that it
delineates lines within the text. Note that this isn't something I do
often, so please read the docs for yourself, and CAVEAT EMPTOR. =o)
