Email sent only to Gmail acct

I have not been receiving form submissions to the user@bossproductsinc.com inbox. I see the submissions in the database archive and when I change the recipient in the form MAIL tab to my gmail address, it is received. I’ve tested my user@bossproductsinc.com spam and junk folder and nothing shows there. I also can send and receive emails just fine at user@bossproductsinc.com. I don’t know how to troubleshoot this.
