I have moved recently my website to a VPS everything working well except for the email.
Emails are delivering well on any domain other than the domain where website is hosted. E.g. emails are sent to @gmail.com @yahoo.com or @anyotherdomain.com. But on domain www.mywebsite.com this is where website is hosted and if i send email like email@example.com I got bounce back stating "Unknown user: sale"
Please help me in fixing this problem. I am thinking this could be MX record issue but I am not sure.
For email service I am using office 360.
