    Unable to Send Email Invitations while inviting a Umbraco user

    Email Invitation is Failing while inviting the user even after having valid Amazon SES Credentials in the SMTP Configuration. Amazon SES Credentials are working in other application bit not in the Umbraco. Here is the error while Inviting the user.

    "System.Net.Mail.SmtpException: Transaction failed. The server response was: Message rejected: Email address is not verified. The following identities failed the check in region US-WEST-2: [email protected]\r\n at System.Net.Mail.DataStopCommand.CheckResponse(SmtpStatusCode statusCode, String serverResponse)\r\n at System.Net.Mail.DataStopCommand.Send(SmtpConnection conn)\r\n at System.Net.ClosableStream.Close()\r\n

    Hi Anil,

    It appears as though your application is trying to use the default email address, being [email protected], to send your mail! Please double check that both your SMTP settings in the web.config are configured properly, and that you have specified the mail that Umbraco should use for sending out notifications in the /config/umbracoSettings.config file!

    Kind regards,
