subject "Hello Fred"
body 'How are you?'
}
what am I doing wrong?
solution

Answer 1

The error say Unable to locate provider for protocol: smtp. It seems you're missing some dependencies for the smtp protocol, which seems very odd, apparently you're missing javamail (?). Because the code seems good to me.

Answer 2

Have you tried to remove
"mail.smtp.port":"465",
"mail.debug":"true",
from your config? This is the only difference I see between your code and the official example.
Update: as GalmWing already stated, it seems to be a problem with your java.mail jar file. Please check this solution: Using Java to send emails on gmail account . It sounds to me like you have the same problem. Which java-version do you use?

Answer 3

add to config.groovy
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "email"
password = "pwd"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
use this code to send mails
def sendEmail(){
mailService.sendMail {
to "email","**email**"
from "email"
subject "Hi"
body 'Hi'
}
}
also dont forget to inject mailservice in your class
def mailService
this will inject the service to your class
and this configuration will be sufficient to send mails
