Email Not Receiving Emails (but can still send emails)

Email Not Receiving Emails (but can still send emails)

Hi,

For some reason, my email is not receiving email messages. I can send them but not receive them. Before now, it was fine!

I have checked my MX Records and they are pointing correctly. When I try to send a test email I get the message:

"553 Relaying disallowed"

Can anyone help?

Thanks,

Becky
