I wrote a script that checks how many emails we have on our account and then, when we write id(number), the script will write the subject of this email. 
#!/usr/bin/perl
use warnings;
use strict;
use Net::POP3;

my $time = scalar localtime;
my $pop3 = "pop3.poczta.onet.pl";
my $login = "haptor\@op.pl";
my $pass = "*************";

my $pop = Net::POP3->new($pop3);

my $res = $pop->login($login, $pass);
if ($res eq "undef"){
print "Couldn't connect $!\n";
exit;
} else {
print "On $time e-mail status inbox: $res post \n";
}

print "Write id(number) email to read:\n";
chomp(my $msgnum = <STDIN>);

my $msg = $pop->get($msgnum);
if($msg =~ /Subject:(.*)From:/){  #I think that there is a error here
print "Subject is $1";
}

$pop->quit();

I want to extract the subject from the e-mail but $1 is empty.... I don't know what i do wrong... Maybe Regexp or bad variable.
