|Understanding Mail Delivery Failure Transcripts|
Account Specific errors:
User unknown/invalid user/Mailbox unavailable: These errors indicate that the recipient's account does not exist. If you see this error, please ensure you've typed the correct email address in the To; box. If you've typed the correct address, please 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.
Message exceeds the size limit: This indicates that you tried to send a message that was larger than the acceptable size limit set by the recipient's email provider. If possible, try breaking up the message into smaller parts and re-send them.
Service unavailable: This error message can have multiple meanings. If you see this in the transcript, forward the message with the transcript and full headers to BlueLight Internet email support for further investigation.
Mail Quota Exceeded/Mailbox Disk Quota Exceeded: This message indicates that the recipient's mailbox is full, and cannot accept any more emails. To resolve this, contact the recipient and ask them to clear their mailbox.
Domain Specific errors:
Host unknown: This message indicates that the domain to which the mail was sent does not exist. Contact the recipient and verify their correct email address (including the domain name) and try sending the mail again.
Deferred: Connection timed out with mail.recipient.com/ Message could not be delivered for 3 days: This message indicates that the failure occurred because of a temporary problem. Try sending this message again at a later time. If the problem persists after trying again, have the recipient contact their domain administrators.
Domain block: This message means the recipient's domain has placed a block either on your email address or on all mail originating from your domain. The following messages indicate a possible domain block:
1. "Access denied"
An "Access denied" error transcript appears if email sent to a BlueLight Internet email address is blocked by BlueLight Internet's anti-spam filters.
A sample of the Access denied error transcript is shown below for your reference:
550 Access denied...2ab079a1b0b0ddddc9a0c979793dd9d901e0e0e9e50489118d4d45e10d84d19444
To resolve this issue, please forward the entire mail delivery failure notice (including the complete Access Denied error transcript) to firstname.lastname@example.org along with a detailed description of the problem or situation.
Please note: The complete Access denied code includes the string of random alphanumeric characters having three dots ("...") as the prefix as well as the suffix.
This information will help us investigate why the message triggered BlueLight Internet's anti-spam filters, and take appropriate action.
2. This domain is banned / This domain is banned for spamming / Message from domain BlueLight Internet.com is rejected / unsolicited mail is refused
The above error messages all indicate that email sent to a non-BlueLight Internet email address was blocked by the recipient domain. The block could pertain to just the individual message, or to all messages sent from BlueLight Internet.
To resolve this issue, contact the recipient to inform them of this situation, and have them contact their domain and let them know they wish to receive mail from BlueLight Internet.
You can also forward the entire mail delivery failure notice to email@example.com along with a detailed description of the problem or situation.
BlueLight Internet does contact the recipient's domain to resolve these issues, however, domains often respond most quickly to reports from their own users.
