I cannot receive messages on .net domains

[crossing]

Helo,

I just added new .net email on my kloxo-mr panel and initially received one confirmation email from twitter then nothing. I made countless tests with no results.  I can login via webmail.mydomain.net and send emails but I cannot receive any email no more. All my old emails or any other .com ,etc  I create works fine. Only this .net domain makes me this problem.   What could be the problem ?

ps. forwards works.
