Not recieving incoming emails from specific mail adress

Not recieving incoming emails from specific mail adress

Hello,
      I just implemented Zoho mail in my organization and i have certain trouble with one mail account, I am not reciving mails from one specific address. It's domain is not in my blacklist, neither the mail address; actually any other mail account from my organization are able to recieve mails from that account. Is there a way for me to check the log of my server to determine where does mails are going?

Thanks!
