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

If you'd want your application that to login to the SMTP server (Since you are providing authentication details). Just change

props.put("mail.smtp.auth", false); 

to

props.put("mail.smtp.auth", true);
