Delivery Failures
Your message
To: address@domain.com
Subject: {Subject Title}
Sent: {Date] {Time} {Time Zone}
did not reach the following recipient(s):
Variation 1:
address@domain.com on {Date] {Time} {Time Zone}
The destination server for this recipient could not be found in Domain
Name Service (DNS). Please verify the email address and retry.
If that fails, contact your administrator.
<{Issuing Server} #5.4.0>
Variation 2:
address@domain.com on {Date] {Time} {Time Zone}
The e-mail system was unable to deliver the message, but did not report
a specific reason. Check the address and try again. If it still fails,
contact your system administrator.
<{Issuing Server} #4.0.0 smtp;450 <address@domain.com>: Sender address
rejected: Domain not found>
Explanation:
This non-delivery report provides the relevant information about the
email and the error which has occurred. The {Issuing Server} is
not always the server that the error has occurred at but rather the
server that issued the error message to the 'Sender'.
The phrase "The
destination server for this recipient could not be found in Domain Name
Service (DNS)." and "Sender address
rejected: Domain not found" indicate the cause. The errors
are self
explanatory, the
stated domain "@domain.com" is not a
registered domain name and therefore the email cannot be delivered to
it.
Conclusion & Action
Required:
The sender should ensure that the email address is correctly
typed. If email address is correctly spelt, then the sender should
contact the recipient to enquire as to whether the email address has
been provided incorrectly or if their service provider's servers have a fault.
The recipient should contact their service
provider to enquire as to the cause of the error, or provide the sender
with the correct email address.
