Sending emails works fine. unable to recieve

About 2 weeks ago I sent out a bunch of emails and got no responses. After checking, all of the recipients got the email and responded. I got none of those responses. Since then I have tested  the account and sure thing, if I send it FROM dan@dandennisvo.com it goes fine. But if I respond or send it TO  dan@dandennisvo.com it goes to never-never-land. I haven't changed any settings and it doesn't matter what device  i use. Any thoughts??
