not receiving mail

Hi there, hope you're well

I have a problem with one of my mails. When I send mail from sdasilva@dasilva.com.uy to secretaria@dasilva.com.uy the mails seems to desappear. They're not on spam and they don´t bounce either. From secretaria@dasilva.com.uy to sdasilva@dasilva.com.uy (the other way) they are delivered correctly. Could you check the logs please? what could be the problem? Also I'm not receiving mails from the domain cebra.com.uy
Thank you very much
Marcelo
