Environment: Oracle 10g (10.1.0.2.0) standard edition on Windows 2003 server

I need to install utl_mail package and this is the link I am working with http://download-east.oracle.com/docs...802/u_mail.htm

The link above asks says:

------------------------
Operational Notes
You must both install UTL_MAIL and define the SMTP_OUT_SERVER.

To install UTL_MAIL:
sqlplus sys/
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
SQL> @$ORACLE_HOME/rdbms/admin/prvtmail.sql


You define the SMTP_OUT_SERVER parameter in the init.ora rdbms initialization file. However, if SMTP_OUT_SERVER is not defined, this invokes a default of DB_DOMAIN which is guaranteed to be defined to perform appropriately.
--------------------------

I successfully ran and installed utlmail.sql, but the issue is I don't see prvtmail.sql file exist but only prvtmail.plb. So how do I run SQL> @$ORACLE_HOME/rdbms/admin/prvtmail.sql
to install SMTP_OUT_SERVER.

Please help.
