JavaMail with MS Exchange: No authentication mechansims supported by both server and client

Question

I\'ve been trying for days now to send mail from Grails application and unsuccessfully. I\'m using:

• grails 1.3.7
• mail 1.0 plugin
• spring-secur

Answer 1

Here's my solution, maybe it's not the best way, but it works for me...

in the mail-config.xml:

    
    
    
    
    
    
    
    
        
            ${mail.auth}
        
    

and here's the setting:

mail.from=XXX Team 
mail.host=exchange.xxx.com
mail.port=25
mail.protocol=smtp
mail.auth=false
mail.username=
mail.password=

and finally, the code:

package com.xxx.service;
import org.springframework.mail.javamail.JavaMailSenderImpl;

public class MailSender extends JavaMailSenderImpl {

    private boolean authRequired;

    @Override
    public String getUsername() {
        if (!authRequired) {
            return null;
        }
        return super.getUsername();
    }

    @Override
    public String getPassword() {
        if (!authRequired) {
            return null;
        }
        return super.getPassword();
    }

    public boolean isAuthRequired() {
        return authRequired;
    }

    public void setAuthRequired(boolean authRequired) {
        this.authRequired = authRequired;
    }

}
