程序如下：
options emailsys=SMTP;
options emailauthprotocol=LOGIN;
options emailhost="smtp.qq.com";
options emailid="22222@qq.com";
options emailpw="222222";
options emailport=25;

filename mymail EMAIL "11111@163.com" subject="测试" encoding=gb2312;
data _null_;
file mymail;
put '测试邮件：祝新年快乐！';
run;

filename mymail clear;


报错如下：
ERROR: 电子邮件: 530 Error: A secure connection is requiered(such as ssl). More information at

需要对程序如何调整，求教，非常感谢。
