My Email again does not appear to be working!

[Eides]

HELP - my email - max@benefitplace.biz - again does not appear to be working! When I send myself a message from a different email address, nothing arrives in my inbox or the forward! When I just went to the cpanel, it said I have no messages! This email is my "Inbound" email for my two websites: www.benefitplace.biz and www.bptradeshow.com While I have no way of knowing when this problem started, I potentially have lost thousands of dollars! Is there a way to retrieve previous messages?

Please let me know what is wrong!

Thanks,

Phil
