I go the folowing messge from my remote server when i run index.pl with the above code. RCPT TO: error (550 relay not permitted). That means that i can only sends mails using sendmail with recepients of the same domain? And if so what can i do to mail to others throuh my page? 
%mail = ( To      => 'nik0s@mycosmos.gr',
          From    => 'roufianos@kyp.gr',
          Subject => "Επισκέπτης από $host"
        );
sendmail(%mail) or die $Mail::Sendmail::error;
