There are several possible caused for mail delivery failures, such as problems with your or the recipient's email account (i.e. account specific) or the sending or receiving domain (i.e. domain specific).

The list below has some common errors contained in the transcript and will help you understand why you got a mail delivery notice.
Account Specific errors:
User unknown/invalid user/Mailbox unavailable:
These indicate that the recipient' s account does not exist. If you see this, check to make sure you' ve typed the correct email address in the To; box. If so, contact the recipient some other way to verify their email address and try sending the mail again.
Account Inactive:
This indicates that the recipient' s account is currently inactive. If the recipient is a BlueLight Internet member they should log in to the BlueLight Internet software to reactivate their account. If the recipient is not a BlueLight Internet member, they should contact the technical support of their email service provider to find out how to reactivate the account.
