Maybe perl has some module to handle this but I use "Blat" for NT and "MAIL" for Unix. These 2 subs should help. You need to open your logfile and check for an error string. If you catch it you will get an e-mail. 
sub Notify    {
 local $Message = $_[0];
 &MailMessage(${MailList},"***${JobName}: ${Host}: ${Message} ${LogFil
+e}",${LogFile},${Host} );        
};

sub MailMessage {
 # This file will send mail to the recipient with the given subject.
 # If the body is supplied, it will also be sent.  If a sender is
 # supplied, the message will be marked with that sender in the "From"
 # field.

 local $Recipient = $_[0];
 local $Subject   = $_[1];
 local $Body      = $_[2];
 local $Sender    = $_[3];

       $Recipient =~ s/\n+//;
       $Subject   =~ s/\n+//;
       $Sender    =~ s/\n+//;

 if (!defined $MailFile) {
  if ($OSFlag ne "Y") { &DefineOS; };
  $MailFile = "${Temp}/mis_mail.$$";
 };

 if (-r $Body) {

  open (MAILFILE, "> $MailFile");
  open (BODY,     "$Body");
  while (<BODY>) { print MAILFILE "$_"; };
  close (BODY);
  close (MAILFILE);

 } else {

  open (MAILFILE, "> $MailFile");
   print MAILFILE "$Body";
  close (MAILFILE);

 };

 if ($OS eq "MSWin32") {
  $Mail = qq! $Mail $MailFile -t "$Recipient" -s "$Subject" ! .
          qq! -i "$Sender" -f "$Sender" !;
print "using blat...\n";
  open (MAIL, "| $Mail");
  while (<MAIL>) { print $_; };
  close (MAIL);
 print "closing blat...\n";
 } else {

 open (MAILFILE, "$MailFile");
 open (MAIL, "| $Mail $Recipient");
  print MAIL "To: $Recipient\n";
  print MAIL "From: $Sender\n";
  print MAIL "Subject: $Subject\n";
  while (<MAILFILE>) { print MAIL $_; };
  print MAIL "\n.\n";
 close (MAIL);
 close (MAILFILE);

 };

 $mesg = "Mail sent to $Recipient\n";
 LogMessage($mesg);

 unlink ("$MailFile");

 };
