Two suggestions:

  1. Wherever possible, avoid scattering hardcoded constants throughout the code. Instead, aim to make the script easily configurable. As a first step, move any data which could change into a hash:

    my %config ( smtp_destination => '', nas_array_ip_list => 'C:/path/to/nas_array_ip_list.txt', smtp_msg_from => '', smtp_msg_to => '', mail_file => 'C:/path/to/dmcheck.txt', username => 'username', password => 'password', reason => '/nas/sbin/getreason', nasmailmsg_from => '', nasmailmsg_to => '', dm_check => 'dmcheck.txt', );

    and access the hash data as needed:

    MIME::Lite->send('smtp', $config{smtp_destination}); if (! open my $fh, '<', $config{nas_array_ip_list}) ...

    As the next step, you may find it useful to populate the hash by reading in the data from a separate configuration file.

  2. Avoid system calls where Perl has equivalent built-in functions. So, replace

    system 'del dmcheck.txt';


    unlink $config{dm_check} or warn "Could not unlink file '$config{dm_ch +eck}': $!";

    See unlink.

Hope that helps,
