Not gettting email in by Email Tab but only from myself.

Not gettting email in by Email Tab but only from myself.

OK this is weird.  If I send email to anyone outside my POP email domain there is not problem but if I send email to myself or anyone else in our company email domain no one is getting the email.  If I look in the Zoho email tab the email is not there but If I go to my record under "Contact" and look at the email tab the email is there.  I want the email to show up in my email tab (with all my other email).  This worked fine a few days ago so I'm not sure what happened.  I am not at my email limit.
