Set the subject of the mail

Question

Hi,
Here is one working example
create or replace
procedure testing_mail
IS
mailhost VARCHAR2(30) := '10.?.5.?';
mail_conn utl_smtp.connection;
crlf VARCHAR2( 2 ):= CHR( 13 ) || CHR( 10 );
mesg VARCHAR2( 1000 );
BEGIN
mail_conn := utl_smtp.open_connection('10.?.5.?', 25);
mesg:= 'Date: ' || TO_CHAR( SYSDATE, 'dd Mon yy hh24:mi:ss' ) || crlf ||
'From: <'postmaster@mysmtpdomain'||'>' || crlf ||
'Subject: '||'testing mail' || crlf ||
'To: '||'[email protected]'|| crlf ||
'' || crlf || 'Testing mail procedure';
utl_smtp.helo(mail_conn, '10.?.100.?');
utl_smtp.mail(mail_conn, 'postmaster@mysmtpdomain');
utl_smtp.rcpt(mail_conn, '[email protected]');
utl_smtp.data(mail_conn, 'Testing mail procedure');
utl_smtp.quit(mail_conn);
END;
But I need the idea to put the subject for the successful example above!
Best Regards

Do not invent your own linefeed combinations. Use the linefeed constant from the UTL_TCP package.
As for formatting the e-mail itself - that is governed by the specs for MIME bodies.
Have a look at the basic explanation at http://en.wikipedia.org/wiki/MIME and read the relevant RFCs that contains detailed specifications on how to construct MIME bodies.
