here's the the code, the regex for Deferred is working now, but still I am running out of idea how store multiple recipients associating with the qid, any idea?

#!/usr/bin/perl
use Data::Dumper;

open (Q,"-|" , "cat mailqout" );
my $ref_tomailq= [];
my $coutner = 0;
my $temp_qid;
while(<Q>) {
        # Ignore the banners and totals
        next if  m{ Q-ID  }ix ;

        # Ignore any completed jobs
        #next if m{ ^ .{10,20} \s \(job \s completed\) }x;

        if( m{ ^\w+ }ix ) {
                my @ar_line = split(/\s+/,$_);
                my $num_char = length($ar_line[0]);
                if (  $num_char > "0") {
                        #print "$ar_line[$counter] $ar_line[-1]";
                        $ref_tomailq->[$counter]->{$ar_line[0]}->{"fro
+m"} = $ar_line[-1];
                        $temp_qid = $ar_line[0];
                        $counter++;
                }
        } else {
                my @ar_line = split(/\s+/, $_);
                chomp(@ar_line);
                if ( $ar_line[1]  =~ /\(Deferred:/) {
                        $ref_tomailq->[$counter-1]->{$temp_qid}->{"sta
+tus"} = "deffered";
                } elsif ($ar_line[1] =~ /<{1}\w+>?/) {
                        #print "@ar_line\n";
                        $ref_tomailq->[$counter-1]->{$temp_qid}->{"to"
+} = $ar_line[1]
                }
        }
}

print Dumper($ref_tomailq);
