Spickachu has asked for the wisdom of the Perl Monks concerning the following question:

I feel like this is sorta cheating. It's crude but I don't get paid enough to do anything more fancy for now! 
# file: Mailq_Check.pl

open STDOUT, ">mailq_check.log";
system "mailq | grep frozen";
close STDOUT;

exec `perl mail_report.pl mailq_check.log`;

# file: mail_report.pl

while (<>) {
    @array = $_;
    $mail_fault_cnt++;
}

if ( $mail_fault_cnt > 0 ) {
    exec `more mailq_check.log| mail -s MailQ_Error sstock\@essex.ac.u
+k`;
}

    Open a pipe to mail and send to output of mailq to it. 
    $output = `mailq | grep frozen`;
if ($output) {
  open(MAIL, "| mail -s sstock\@essex+.ac.uk");
  print MAIL $output;
  close(MAIL);
}

    Sorta cheated and used the quick and easy response in the end. So it's crude but don't get paid enough to doing anything more fancy for now! 
    --------------------------------------------------
         <FILENAME:  Mailq_Check.pl>

open(STDOUT, ">mailq_check.log");
system("mailq| grep frozen");
close STDOUT;

exec(`perl mail_report.pl mailq_check.log`);

--------------------------------------------------
         <FILENAME:  mail_report.pl>

while (<>) {
        @array = $_;
        $mail_fault_cnt++;}

if ($mail_fault_cnt>0) {
        exec (`more mailq_check.log| mail -s MailQ_Error sstock\@essex
+.ac.uk`);}
