blocked email domains for free demo host

Last 2 weeks we have too many requests from anonymised emails like – mailnesia.com and other temporary email services. We have to block all those email addresses and do not allow registration with temporary mail. The main reason is that 1 person could take all our demo servers and don’t reply to our mails. If you still want to use temporary mail – pls write mail to us at sales@javanode.com
