Security Model

UTL_MAIL is not installed by default because of the SMTP_OUT_SERVER configuration requirement and the security exposure this involves. In installing UTL_MAIL, you should take steps to prevent the port defined by SMTP_OUT_SERVER being swamped by data transmissions.

This package is now an invoker's rights package and the invoking user will need the connect privilege granted in the access control list assigned to the remote network host to which he wants to connect.

Note:

For more information, see Managing Fine-grained Access to External Network Services in Oracle Database Security Guide

Operational Notes

You must both install UTL_MAIL and define the SMTP_OUT_SERVER.

To install UTL_MAIL:

sqlplus sys/<pwd>
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
SQL> @$ORACLE_HOME/rdbms/admin/prvtmail.plb

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.

Rules and Limits

Use UTL_MAIL only within the context of the ASCII (American Standard Code for Information Interchange) and EBCDIC (Extended Binary-Coded Decimal Interchange Code) codes.
