	Unable to send message (503 Error: nested MAIL command)

Solution Use the SMTP logging to determine what is occurring when the message is being sent.

Most likely, this error occured because the email address being sent to was not a "real" email address or was mistyped. If you send to multiple addresses and 5 email addresses are correct and one was not, the entire transaction is terminated.
