Does AWS SES work with grails Mail plugin 1.0.7? - amazon-web-services

Question

I would like to use the AWS SES mail service using SMTP. I know it works for some versions, but I haven't gotten it to work for my application yet. I get a 530 Authentication error.
My question is in three parts:
1. Does AWS smtp work using Grails 2.3.1 with the Mail 1.0.7 plugin using java 1.7?
If it does work, how does one configure it?
If it does work, how can I get more debug information to figure what is wrong?
I've tried every configuration example variant I've come across for this. My latest is below. (It's clear I don't really understand the Mail plugin and the Java mail class, I'm just trying to suss out a working configuration incantation.)
Here is what I have in my config.groovy file:
grails {
mail {
host = 'email-smtp.us-east-1.amazonaws.com'
port = '587'
username = SMTP AWS username, not IAMS username
password= SMTP AWS password, not IAMS password
props = [ 'mail.debug': true,
'mail.smtp.host' : 'email-smtp.us-east-1.amazonaws.com',
'mail.smtp.auth': 'true',
'mail.smtp.starttls.enable': 'true',
'mail.smtp.port': '587',
'mail.smtp.starttls.required': 'true',
'mail.smtp.user' : smtp username from above,
'mail.smtp.usernme' : smtp username from above,
'mail.smtp.password': smtp password from above,
'mail.smtp.socketFactory.port': '587',
'mail.smtp.socketFactory.class':
'javax.net.ssl.SSLSocketFactory',
'mail.smtp.EnableSSL.enable':'true',
'mail.smtp.socketFactory.fallback': 'false' ]
}
}
I have successfully made direct AWS SES emails using the aws-sdk:1.9.40 plugin, by the way.
I am using the mailService.sendmail code from the Mail plugin. This is unchanged (beyond the hardcoded html text), and works fine when the configuration went to our email server.
def resp = mailService.sendMail {
from replyToEmail
replyTo replyToEmail
to user.email
subject emailSubject
html "This is the mesage text Mar 20"
}
Any help at all would be most appreciated!!
