AspSmartMail 503 Authentication Error

If you are using the AspSmartMail component to send emails on a Windows server and set mySmartMail.Server = "mail.yourdomain.com" you will receive the following error-:

Error: Error when check Recipient address : 503 This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

This is because of the tight security settings we run on our servers to reduce spam and email hijacking. To send emails from AspSmartMail use the following in your script.

mySmartMail.Server = "127.0.0.1"
