Explanation of how messages can appear in the bad mail directory.
Mail will only go into bad mail directory under the circumstances listed below. If messages are stuck in the outbound queue, there would be a reason for this. One suggestion is to check the SMTP debug log in the Mail Enable\Logging\SMTP directory, as this will contain details of why messages fail, and also why messages go into bad mail. Sending between users usually only fails if the email address was not a valid user. A message is not fully received by the MailEnable SMTP service. The last line of the MAI file in the Bad Mail\Messages directory will indicate the error that caused this.
