Perl Question

[Aella]

Hi

 

I found this script which is supposed to mail me when a file not found error has occured.

 

 

use Mail::Mailer;

# create the body of our HTML and mail message.

  my $body = "File not found!\n";

  $body .= "Here's the environment I was called with:\n\n";

  while ( my ($var, $val) = each %ENV ) { $body .= "  $var = $val\n"; }

 

  # mail our warning off.

  my $mailer = Mail::Mailer->new("sendmail");

  $mailer->open({ From    => "404\@aellalei.com",

                  To      => "aella\@aellalei.com",

                  Subject => "A 404 Has Been Detected!",

                });

  print $mailer $body;

  $mailer->close();

 

I put it in my 404 error document, and it works... sort of. I get a message in my inbox saying "This message was created automatically by mail delivery software.

 

 

A message that you sent could not be delivered to one or more of its

recipients. This is a permanent error. The following address(es) failed:" It goes on to say that it failed to lock mailbox.

 

What does that mean "failed to lock mailbox"? Is that something I can fix?

 

Thanks!
