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); }
