本篇是通过Oracle10g发送Email实例，该Procedure支持中文邮件、HTML代码、多收件人。
在Procedure中p_receiver为收件人地址，多收件人以“,”（英文逗号）分割，
p_sub为邮件标题，p_txt为邮件内容（支持HTML）。代码如下：

create or replace procedure bsd_sendemail (p_receiver varchar2,p_sub varchar2,p_txt varchar2)    is    p_user varchar2(30) := '';    p_pass varchar2(30) := '';    p_sendor varchar2(20) := 'Gnie';    p_server varchar2(20) := 'Mail_Server_IP';    p_port number := 25;    p_need_smtp number := 0;    p_subject varchar2(4000);    l_crlf varchar2(2) := utl_tcp.crlf;    l_sendoraddress varchar2(4000);    l_splite        varchar2(10) := '++';    boundary            constant varchar2(256) := '-----BYSUK';    first_boundary      constant varchar2(256) := '--' || boundary || l_crlf;    last_boundary       constant varchar2(256) := '--' || boundary || '--' || l_crlf;    multipart_mime_type constant varchar2(256) := 'multipart/mixed; boundary="' || boundary || '"';      type address_list is table of varchar2(100) index by binary_integer;    my_address_list address_list;    ---------------------------------------分割邮件地址----------------------------------------------    procedure p_splite_str(p_str varchar2,p_splite_flag int default 1) is      l_addr varchar2(254) := '';      l_len  int;      l_str  varchar2(4000);      j      int := 0; --表示邮件地址或者附件的个数    begin      /*处理接收邮件地址列表，包括去空格、将;转换为,等*/      l_str := trim(rtrim(replace(replace(p_str, ';', ','), ' ', ''), ','));      l_len := length(l_str);      for i in 1 .. l_len loop        if substr(l_str, i, 1) <> ',' then          l_addr := l_addr || substr(l_str, i, 1);        else          j := j + 1;          if p_splite_flag = 1 then --表示处理邮件地址            --前后需要加上'<>'，否则很多邮箱将不能发送邮件            l_addr := '<' || l_addr || '>';            --调用邮件发送过程            my_address_list(j) := l_addr;          end if;          l_addr := '';        end if;        if i = l_len then          j := j + 1;          if p_splite_flag = 1 then            --调用邮件发送过程            l_addr := '<' || l_addr || '>';            my_address_list(j) := l_addr;          end if;        end if;      end loop;    end;    ------------------------------------------------写邮件头和邮件内容------------------------------------------    procedure write_data(p_conn   in out nocopy utl_smtp.connection,                         p_name   in varchar2,                         p_value  in varchar2,                         p_splite varchar2 default ':',                         p_crlf   varchar2 default l_crlf) is    begin      /* utl_raw.cast_to_raw 对解决中文乱码问题很重要*/      utl_smtp.write_raw_data(p_conn, utl_raw.cast_to_raw(convert(p_name||p_splite||p_value ||p_crlf, 'ZHS16CGB231280')));    end;    ----------------------------------------写mime邮件尾部-----------------------------------------------------    procedure end_boundary(conn in out nocopy utl_smtp.connection, last in boolean default false) is    begin      utl_smtp.write_data(conn, utl_tcp.crlf);      if (last) then        utl_smtp.write_data(conn, last_boundary);      end if;    end;    ---------------------------------------------真正发送邮件的过程--------------------------------------------    procedure p_email(p_sendoraddress2 varchar2, --发送地址                      p_receiveraddress2 varchar2) --接受地址     is      l_conn utl_smtp.connection; --定义连接    begin      /*初始化邮件服务器信息，连接邮件服务器*/      l_conn := utl_smtp.open_connection(p_server, p_port);      utl_smtp.helo(l_conn, p_server);      /* smtp服务器登录校验 */      if p_need_smtp = 1 then        utl_smtp.command(l_conn, 'AUTH LOGIN', '');        utl_smtp.command(l_conn, utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw(p_user))));        utl_smtp.command(l_conn, utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw(p_pass))));      end if;        /*设置发送地址和接收地址*/      utl_smtp.mail(l_conn, p_sendoraddress2);      utl_smtp.rcpt(l_conn, p_receiveraddress2);        /*设置邮件头*/      utl_smtp.open_data(l_conn);      /*设置日期*/      --write_data(l_conn, 'Date', to_char(sysdate-1/3, 'dd Mon yy hh24:mi:ss'));      /*设置发送人*/      write_data(l_conn, 'From', p_sendor);      /*设置接收人*/      write_data(l_conn, 'To', p_receiver);      /*设置邮件主题*/      select replace('=?GB2312?B?'||utl_raw.cast_to_varchar2(utl_encode.base64_encode(rawtohex(p_sub)))||'?=',utl_tcp.crlf,'')
