I am getting authentication error while sending mail throug logstash. below is my Email configuration I set ``` email { debug => true authentication => "login" address => " **my mail server IP**" port => 25 username => " **service account name**" password => " **service account password**" body => "text mail to check notification" from => " **my mail id**" subject => "Test mail to check notification" to => " **my mail id**" } ``` I am getting below error [2017-02-08T09:39:02,129][ERROR][logstash.outputs.email] Something happen while delivering an email {:exception=\>#\ } am I missing any mail parameter which is causing this error or I have to set different value for authentication? ---

Try setting `authentication` to "plain". If that doesn't help, please telnet to port 25 of your email server, type `EHLO yourhostname` (insert your hostname) and report the response. It should look similar to this but hopefully with an AUTH line: ```nohighlight 250-PIPELINING 250-SIZE 25067520 250-VRFY 250-ETRN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN ``` ---

> [@magnusbaeck](#): > > yourhostname Thank you Magnus. but setting authentication to "plain" did not work. here is the response after running EHLO hostname: EHLO **host name** 250- **host name** Hello [**IP**] 250-SIZE 36700160 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-8BITMIME 250-BINARYMIME 250 CHUNKING I have removed server specific detals for privacy.. ---

That server doesn't offer SMTP authentication. Switch to one that does or disable authentication on the Logstash side. ---

Thank you. in our email server, authentication was not enabled and after removing the authentication entry, I was able to generate the mail. ---
