When I try to send emails I show this error:

INVALID_ADDRESS, ERROR_CODE :550, ERROR_CODE :Please turn on SMTP Authentication in your mail client, or login to the
			IMAP/POP3 server before sending your message

After review other forum posts, I showed that this error is caused when Zoho Mail doesn't recognize the MX records, because I set the MX records point to Zoho, but Zoho Mail doesn't recognize it. You can view this in:

Can you enable the mail service please? I need it as soon as possible...

Thanks in advance
