When there are so many pure-Perl mail tools at your disposal, why use blat? Here's a sample using Mail::Sendmail, which is installable with PPM if you're using ActivePerl.

  use Mail::Sendmail;

  my $fromsender='someone@somewhere.com';
  my $subject="Data";
  my $CustomerNumber = param("CustomerNumber");
  my $Name = param("Name");
  my $Address1 = param("Address1");
  my $City = param("City");
  my $State = param("State");
  my $ZipCode = param("ZipCode");
  my $Email = param("Email");
  my $server="server.name.net";
  my $recipient='someoneelse@somewhereelse.com';
  my $bccaddress = 'wheredidI@comefrom.com';

  my $message="$CustomerNumber.$Name.$Address1.$City.$State.$ZipCode.$
+Email";

  my %mail = ( 
      Subject => $subject,
      From    => $fromsender,
      To      => $recipient,
      smtp    => $server,
      Message => $message,
      Bcc     => $bccaddress );

  Mail::Sendmail::sendmail( %mail );
  if ( $Mail::Sendmail::error ) {
     # ... display the error in $Mail::Sendmail::error
     # or however you wish to handle it
  }

  # everything else below this is for displaying HTML
  # and not relevant to this post...

Two other things:

Using single-quotes (') when creating strings means you don't have to escape the '@' character as you had in your original code.

I used 'my' to initialize all your variables so it would run under use strict;, which is highly recommended. It will save you more time than you know. It pointed out, for instance, that $bccaddress was never initialized.
