Exchange server config. for sending mail to ext

Hi All,

With the help of sap note 455140,455127,552616 i configure the sap level config. to send mail from SAP level to external server.Now we have to configure the exchange server which we are using.But i don't have any idea what to configure in exchange server.We are using MS Exchange server 2003.

Again i got a sap Note 594428 - SXC: Exchange 2003 Server is not supported.Is it true or there is some other way to send mails from SAP system to externel server using MS exchange server 2003.

Regards,

Jitu
