In addition to geoand's answer: if you don't want to hard code the mail properties or to write XML, you can add your properties to a file (mail.properties for example) in your resources, and add this kind of code in the MailConfig class:

@Resource(name = "mailProperties")
private Properties mailProperties;

@Bean(name = "mailProperties")
public PropertiesFactoryBean mapper() {
    PropertiesFactoryBean bean = new PropertiesFactoryBean();
    bean.setLocation(new ClassPathResource("mail.properties"));
    return bean;
}

And the range of properties you can use is all defined on these pages

But you'll still have to set Host, Port, Username and Password from the JavaMailSenderImpl's methods as it wont directly use the ones set in your properties.
