New Roundcube email for new domain is not receiving emails.

I just set up the email for a newly published domain, www.loadplanlogistics.com.  I accessed the inbox for contact@loadplanlogistics.com through the webmail link on the Homestead homepage but the inbox is blank.  There are no folders (inbox, sent, spam) and the email is not receiving emails that I can see.  I am able to send emails.
