Hi Alvin,

This is happening because your SmtpMail.SmtpServer is rejecting addresses.
1. Make sure all email addresses specified at MailMessage.To, MailMessage.Cc, MailMessage.Bcc and MailMessage.From are valid email addresses.
2. Make sure you have permissions to relay through the server.
3. Make sure the MailMessage.From has permissions to relay through the server.

Thanks,
Vijay
