I would approciate help on this program as it generates the following error (the email addresses are not real in this example):

RCPT TO:<validrecipient@validdomain.com>
501 Unknown Command

also

544 no valid RCPT address specified (the address is a valid one, I can send mail using hotmail, MS Outlook Express and Ximian, is it probably because of the 501 error above?)

additionally:
the $smtp->dataend(); generates a 501 unknown command, as does the $smtp->quit;

What am I doing wrong? Or has my ISP implemented ESMTP in a weird way so that Net::SMTP commands are not understood by their server?

Thanks!

Here's the program: 
use Net::SMTP;

sSendEmail('validrecipient@validdomain.com','validrecipient@validdomai
+n.com','ssssssubject','bbbbbbody');

sub sSendEmail {
   my ($to,$from,$subject,@body) = @_;
   my $smtp = Net::SMTP->new('mail.validdomain.com', Debug => 1);
   die "Could not open SMTP connection $!" if  (! defined $smtp);
   print "Connected to: ", $smtp->domain. "\n";
   $smtp->auth('garykuipers@ondacom.biz','judge');
   print "debug:before recipient\n";
   $smtp->recipient($to);
   print "debug:after recipient\n";
   $smtp->mail($from);
   $smtp->data();
   $smtp->datasend("To: $to\n");
   $smtp->datasend("From: $from\n");
   $smtp->datasend("Subject: $subject\n");
   $smtp->datasend("\n");
   foreach my $line (@body) {
      $smtp->datasend("$line\n");
   }
   print "debug:before dataend\n";
   $smtp->dataend();
   print "debug:before quit\n";
   $smtp->quit;
   print "debug:after quit\n";
   print "Mail sent to: |$to|\n";
}
