Grails mail plugin works locally but fails on server - email

Question

I can't get the mail plugin for Grails to work properly on production server with the suggestions out there (such as checking for different versions of plugins)
With the same configuration it works in my local environment.
This is my Config.groovy
grails {
// other configs
mail {
host = "smtp.gmail.com"
port = 465
username = "xxx#gmail.com"
password = "secret"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
} ...
}
EDIT:
This is the exception thrown:
org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is
javax.mail.AuthenticationFailedException:

I know what mailAuthenticationException means, but this works perfectly on local environment, so it's not user/pass data, and the email was configured to allow less secure access on Gmail account. So there should be something wrong in the code.
Im using mail:1.0.7 and grails 2.4.4.
P.D.: I will try on commons email of apache and see what happens...
