It says, that it fails to connect to smtp.gmail.com on port 465. This is not a but in the mail plugin, but rather some connection issue on your localhost.

[sbglasius]

and by the way, it is not recommended to use closures as action definitions in Grails 2.x and up. You should change it to methods instead.

@sbglasius well I have another project that uses mail 1.0.7 on grails 2.4.2 and it's working fine. mail-2.0.0.RC6 on grails 3.1.0 gives me the error on the same config

[sbglasius]

You should try and convert your mail settings to application.groovy and use the old format. I'm not sure that the props: section gets passed back to the mail plugin correctly using application.yml

[ujjwol05]

I even tried that one too.My config on application.groovy

grails {
    mail {
        host = "smtp.gmail.com"
        port = 465
        username = "*********@gmail.com"
        password = "*********"
        props = ["mail.smtp.auth":"true",
                 "mail.smtp.socketFactory.port":"465",
                 "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
                 "mail.smtp.socketFactory.fallback":"false"]
    }
}

And the error is same

This example works: https://github.com/sbglasius/g3-tour-de-plugin-demo/blob/mail/grails-app/conf/application.groovy (notice, that it's on the tag mail)

The presentation is here: https://www.youtube.com/watch?v=RuK90qD6RJU

Notice, that the password in my example is set in an external file.

@sbglasius Today i tried the plugin for grails 3.0.2 and everything is working fine. I guess there is a issue for grails 3.1.0 . I tried installing the plugin several times but still the error is same. Which version of grails did you use for the presentation?

[sbglasius]

I used Grails 3.2.3

[ujjwol05]

Thanks . It worked on other grails version . But there is a issue for 3.1.0
