调试SMTP 邮件服务器（看是否使用了BASE64 编码验证）(debug SMPT server to see if the BASE64 encoding is on )
访问量: 4034
参考： http://help.netmail.com/display/KB/How+to+test+SMTP+AUTH+using+base64+format
1. telnet smtp.yoursite.com 25
2. EHLO (看是否有 auth login )( to see if there's "auth login" string )
3. auth login
auth login 334 VXNlcm5hbWU6 c2hlbnNpd2Vp ( 这里输入 base64 encoded username) 334 UGFzc3dvcmQ6 c3NzMzMzJCQkNDQ0 ( base64 encoded password) 235 2.7.0 Authentication successful
记得，你的邮箱名字一般不要超过20个字！否则会被自动截断！例如： (remember don't make your login name longer than 20 characters length)
notifier-of-push-ops 就很好 (OK! )
notifier-of-push-ops-system 就超过了！ ( 26 digits length! auth will failed! )
