1) JavaMail did not support STARTTLS
javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first. to6sm6813268pbc.12

You just need to download
mail.jar for the newer version of JavaMail. The given examples work with JavaMail-1.4.5.

nslookup is a network administration command-line tool available for many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record.
On Windows, you can type the following:
C:\> nslookup -q=mx myFakeCompany.com
It will show the MX records which have been taken effect.
