Pergunta
I'm trying to figure out why I'm getting an AuthenticationFailedException when the smtp.auth property is set to false. From the debug logs it still attempts to auth login. I've tested the code against a localhost smtp server running on the server which works perfectly fine, but fails when sent to a 3rd party server.
I've tried manually sending an email through telnet, without using authentication and the emails were sent successfully through the 3rd party smtp server so I don't believe its a restriction by the server.
I'm using javamail-1.4.7.
I don't understand why it's attempting to authenticate even though it's disabled

Solução
It's authenticating because you're calling the connect method with a username and password.
It's a bit confusing, but the reason to set mail.smtp.auth to true is to force it to call back to your Authenticator if you call the connect method without a username and password. Setting it to false avoids the callback in that case. But if you explicitly pass in a username and password, as you're doing, it assumes you did that on purpose and that you want to use them to authenticate.
Outras dicas
you can better use SMTPTransport
make it like
SMTPTransport m_transport;
if(mail.smtp.auth is set to false)
{
m_transport.connect(new Socket(getSMTPHost, getSMTPPort));
)else{
m_transport.connect(SMTPHost,SMTPPort,AuthUserAddress,Password);
}
to use Socket you need to import java.net.Socket
