EMAIL - SMTP

sandeepg138 over 7 years ago

Hello,

We have configured gmail account for our server, and I have tested this that Email is being sent.
But It is observed that it is working intermittently. Sometimes the node is failing.
When I try to restart the failed node again then it works fine.

Do I need to make the conf.mailhandler.mail.transport.protocol=smtp as smtps
and port from 587 to 465.
In the log file, error shown is below:
Caused by: javax.mail.MessagingException: Unknown SMTP host: smtp.gmail.com;
nested exception is:
          java.net.UnknownHostException: smtp.gmail.com

This is what I use. Note: I dont have DUAL FACTOR authentication set up in GMAIL. If you do, it might be different.....

conf.mailhandler.mail.smtp.auth=true
conf.mailhandler.mail.user=mygmail@gmail.com
conf.mailhandler.mail.smtp.starttls.enable=true
conf.mailhandler.mail.smtp.starttls.required=true
