SQL & PL/SQL

dear all.
Facts:
- Oracle 9.2.0.4
- AIX 5.3
- mail server 1: suse linux 9
- mail server 2: exchange 2007

i have problem with package utl_smtp. When i put in my own procedure the parameters Cc and/or Bcc shows me the error describe in this thread.
But when i put only the To and From everything is ok.

if i configured my connection through mail server 1 (linux) everything is ok (with Cc and Bcc). But if i configured my connection through mail server 2 (exchange) and send with Cc and/or Bcc shows error.

Both mail servers is configured in order to send mail (relay) and i tested telnet with port 25 and everything is ok.

I searched in metalink and it not shows an error same like i putted and the articles is not that i want:
My code is:
