从Oracle9i中发送电子邮件

Oracle的包utl_smtp提供了从数据库中直接发送电子邮件的功能，这里介绍一下其使用方法

网上找到的例子以及Oracle文档中的例子都没有提到authorized的问题，我的测试中使用的是
163的免费信箱，发送时老是报错：
ORA-20000: Failed to send mail due to the following error:
ORA-29279: SMTP 永久性错误: 553 You are not authorized to send mail as <MAIL FROM:demo@163.com>, authentication is required

后来在metalink上找到解决方法：要在程序中增加登录smtp服务器的过程！

测试环境： RedHat AS 3.0 Oracle 9.2.0.6
SMTP服务器： smtp.163.com(ip地址202.108.44.205）

下面是存储过程的源代码，注意数据库服务器必须要能访问smtp.163.com

CREATE OR REPLACE PROCEDURE send_mail (
p_recipient IN   VARCHAR2,
p_message   IN   VARCHAR2,
p_subject   IN   VARCHAR2 default 'Oracle Perf Report '||to_char(sysdate,'yyyy-mm-dd hh24:mi:ss'),
p_sender    IN   VARCHAR2 default 'demo@163.com')

IS
v_mailhost varchar2(30) := '202.108.44.205'; -- SMTP服务器地址
mail_conn utl_smtp.connection;
msg varchar2(4000);

p_user varchar2(30) := 'demo';       -- 登录SMTP服务器的用户名
p_pass varchar2(30) := 'demo';       -- 登录SMTP服务器的密码

BEGIN
/* 创建要发送的邮件内容注意报头信息和邮件正文之间要空一行 */
msg := 'Date:' ||to_char(sysdate,'dd mon yy hh24:mi:ss') || utl_tcp.CRLF ||
         'From: ' || p_sender || '<'||p_sender||'>' ||utl_tcp.CRLF ||
         'To: '|| p_recipient || '<' || p_recipient || '>' ||utl_tcp.CRLF||
         'Subject: '||p_subject || utl_tcp.CRLF ||utl_tcp.CRLF||
         p_message;

-- dbms_output.put_line(msg);

mail_conn := utl_smtp.open_connection(v_mailhost,25);
utl_smtp.helo(mail_conn,v_mailhost);

/* smtp服务器登录校验 */
utl_smtp.command(mail_conn, 'AUTH LOGIN');
utl_smtp.command(mail_conn, utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw(p_user))));
utl_smtp.command(mail_conn, utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw(p_pass))));

utl_smtp.mail(mail_conn,p_sender);
utl_smtp.rcpt(mail_conn,p_recipient);

/* 发送数据 */
utl_smtp.data(mail_conn, msg);
utl_smtp.quit(mail_conn);

EXCEPTION

WHEN OTHERS THEN
    dbms_output.put_line(dbms_utility.format_error_stack);
    dbms_output.put_line(dbms_utility.format_call_stack);

END send_mail;

测试这个存储过程：
SQL> exec send_mail('demo2@163.com','This is a oracle send mail demo!!!');
