Unable to receive email from a particular mail server

Unable to receive email from a particular mail server

Hello,

I'm unable to receive any mails from a particular mail server at GoDaddy.
(mail.mojolaitsolutions.com)
I have contacted GoDaddy customer support and they have confirmed that
there is no issue from their end.

The email does not bounce back. I am able to receive mails from Gmail.
I am also able to send mails to that particular mail server.

Till last evening, there was no problem. I have not changed the MX records in between.
Kindly help me with this issue.

Thank you
