sendmail not working

I have configured kapacitor SMTP but not getting any emails. my kapacitor.conf is attached. I am using kapacitor 1.3.1 also tried 1.2 sendmail works from the command line, and I wrote a java app to test sendmail and that works fine. I will attach the java code as example.

kapacitor.log
[smtp] 2017/07/07 21:54:17 E! error connecting to SMTP server 535 5.7.0 authentication failed

Start with the attached kapacitor.txt configuration and the SMTP error in kapacitor.log, then compare the settings with TestSmtp.txt and the mail.log connection record. Reproduce the authentication failure and determine whether Kapacitor can send mail successfully with the reported configuration.
