Hello, Please help me investigate what's wrong, I have an Perl script, which check email and post result in IRC. Here is the code:

#! /usr/bin/env perl
use strict;
use warnings;
use IO::Socket;

my $true = 1;

sub exec_module
{

#enable formatting options
        my ( %colors , %format );
# Color Codes
        $colors{blue}  = chr(3) . "02";
        $colors{green} = chr(3) . "03";
        $colors{red}   = chr(3) . "04";
        $colors{brown} = chr(3) . "05";
        $colors{purple}= chr(3) . "06";
        $colors{olive} = chr(3) . "07";
        $colors{teal}  = chr(3) . "10";
        $colors{royal} = chr(3) . "12";
        $colors{pink}  = chr(3) . "13";
        $colors{dgrey} = chr(3) . "14";

#formatting
        $format{bold} = chr(2);
        $format{underline} = chr(31);
        $format{italics} = chr(22);

# Logging options:
# If debug = 1, all messeges are shown
# If debug = 0, only messeges sent with 2 flag are shown
        my $debug = 1;
#logit ( $debug , 1 , "MODULE Generic: error messege" );

        my $sock = shift; # io::sockets referenct to socket info in me
+mory;
        my $channel = shift; # channel bot is opperating in
        my $client = shift; # connection string from IRC (ex: nick!~us
+ername@hostname (ident))

        my $mailcheck = "/usr/bin/env perl /home/tool/imap-connect.pl|
+";
# Pointer to data array use like so:
# $data->[0] =  name of module called
# $data->[1] =  fields 1 and above are data after module call sepereat
+ed by spaces.
# ie (!generic field1 field2) would be $data->[0] = generic, $data->[1
+] = field1 $data->[2] = field2
                my $data = shift;
        while (1) {
                open (HANDLE, $mailcheck);
                while ( my $line = <HANDLE>) {
                        if ( $line =~ /(no mail)/i )
                        {
                                sleep(1);
                        }else{
                                print $sock "PRIVMSG " . $channel . " 
+:" . $format{bold} . $colors{red} . "[mail] " . $line . "\n";
                        }
                        close ( HANDLE );
                }
                sleep(20);
        }
}

It works, but in log I see this error: readline() on closed filehandle HANDLE at modules/alert.pl line 48.
