Logstash Email error : email - Something happen while delivering an email {:exception=>#<Net::SMTPAuthenticationError: Must issue a STARTTLS command first

Hi ,

I am using elk stack of version 7.1.1 + X-pack on unbuntu 14.04 .

i want to trigger a alert whenever the message contains "Exception " keyword in it.

logstash.yml

input {
  file {
    path => "/home/a.log"
    start_position => "beginning"
    codec => multiline {
      pattern => "^%{TIMESTAMP_ISO8601}"
      negate => true
      what => "previous"
     }	
  }
}
filter {

grok {
  match => ["message","[%{LOGLEVEL:log-level}\*%{GREEDYDATA:messagedata}"] 	
	
	}
}
output {
  elasticsearch { 
	hosts => ["localhost:9200"] 
	user => elastic
        password => mypassword 
}
  stdout { codec => rubydebug }

if "Exception" in  [message]{
email {
	to => "v888888888@gmail.com"
	from => "vasadssfrdefd1997@gmail.com"
	subject => "Ignore (2-node envinorment test Alerts)"
	body => "log-message: %{message} \nLog file: %{path}"       
	codec => "plain"
	address => "smtp.gmail.com"
	port => "25"
	       
	}
    }    

}

I am able to write logs into es and console but the email alerts are not working i'm seeing a rare error when i print my logs on console along

please look into the following output on console.

         "log-level" => "debug",
        "@timestamp" => 2019-07-23T15:32:07.651Z,
           "message" => "2019-07-14 09:57:12:001*[debug]*nodejs*req-res-service*sendRequest*990009621098683*88fdad4c-93c3-4e47-88b5-bf9d894863aa*error while sending request.Error: NotLeaderForPartition",
          "@version" => "1",
              "path" => "/home/a.log",
              "host" => "desktop"
}

Please help me solve it.

If you are really going through gmail then you should be using port 587, use_tls should be true, and you will need a valid username and password for a Google account.
