Grails Mail Plugin Office365

Question

I have a code that sends mail using the following config. It works on development (windows, java 1.7, grails 2.3.7) but not in production (ubuntu, tomcat7, jdk 1.7)

Anyone has any idea why this works on dev but not in prod? anyway to fix this?

Sidenote: This code used to work, but suddenly it stop working. Don't know what changed.

Config:

grails {
   mail {
     host = "Outlook.office365.com"
     port = 587
     username = "username here"
     password = "password here"
     props = ["mail.smtp.starttls.enable":"true" ,
                "mail.smtp.port":"587",
                // "mail.debug":"true"
            ]
   }
}

Edit1: Good point in the comments, forgot to include the error. Hope to see some suggestions as fast as the comments! :)

Mail server connection failed; nested exception is com.sun.mail.util.MailConnectException: Couldn&#39;t connect to host, port: Outlook.office365.com, 587; timeout -1; nested exception is: java.net.UnknownHostException: Outlook.office365.com.

Ok guys, after struggling for some time, I found out that the damn dns changed.....

After changing the dns and a restart it went back to normal again.

Thank you for your advice and following up the question.

(Tried to telnet with no response whatsoever. Check dns and tried to ping with no response whatsoever. Couldn't even ping stackoverflow. Changed to some other dns. Restart.)
