Understanding
Undeliverable Email Messages
There are many reasons an email message
may be undeliverable and bounce back to the sender. Some examples are:
 |
Nondeliverable mail: The user's email name is not found
|
|
|
Returned mail: Host unknown. Addresses had permanent fatal
errors |
|
|
Delivery problems with your mail: The domain does not exist?
|
|
|
Error
- Out of office or vacation replies....
|
|
|
Message Failure - Unknown user: or mail box full
|
|
|
Undeliverable mail - User maildir is over quota!
|
|
|
Return mail: Recipient is not in the address book
|
|
|
Failure notice: Name server: host not found. This is a permanent
error. |
|
|
Return mail notice: We have not been able to deliver this
message for 24 hours |
If the mail message was sent, but a
message came back saying it could not be delivered for one reason or
another, try one of the following:
|
|
Check
your sent items box within your mail client and then open the
message that you tried to send and then try resending the message.
|
|
|
Verify
you typed out the full email address in the correct location without
using an address book. Double check the spelling of the recipient's
email. Be sure there are no spaces or commas in the email address
and that the spelling is correct. |
|
|
Contact
the owner of the email address to verify it is valid (most problems
relate to invalid addresses). Check to be sure that the email
address of the recipient has not changed or he/she has not closed
their email account. If you are still receiving returned email, ask
the recipient to contact their ISP for assistance,
|
|
|
The
recipient's mail server may be down. Wait a while and attempt to
send the message again. |
|
|
If
sending an email with a large attachment, attempt to send another
without any attachment. |
Note: Email messages sent from
specific domains may sometimes be blocked due to spam that originates
from their domain. These issues are generally resolved when the owner of
the domain takes action to eliminate the person(s) responsible for
sending the spam.
