Bonjour et merci de m'avoir répondu si rapidement.
Mais j'ai en effet beaucoup de problème avec l'anglais technique et je n'ai pas pu comprendre grand chose de ce texte.
Je le recopie et je laisse le soin de traduire pour moi.
Q. What does “Relay Access Denied” mean?
A. Sometimes an electronic mail message needs to be transferred or relayed across multiple computers or servers on the Internet in order to reach its intended destination. For security purposes many computers or servers on the Internet restrict the IP addresses and/or domains they will accept electronic mail messages from or relay messages for. If a computer or server on the Internet refuses to transfer a message it will create an error message that will be returned to the sender of the refused message.
The most important pieces of information included in bounce messages of this type are the sender and recipient addresses, date of delivery, and the host name or IP address that rejected the message. In order to resolve this issue the Administrator of the host that rejected the message must be contacted.
Here some common examples of this type of bounce message:
Italicized text indicates default information that can be customized by the Administrator of the mail server that created the bounce message.
Underlined text indicates information that is reliant upon the information contained in the original message and pertaining to the specific error experienced when delivery was attempted.
Example 1:
From: System Administrator
Sent: Day, Month Date, Year Time
To: Sender Email Address
Subject: Undeliverable: Subject from the original message
Your message did not reach some or all of the intended recipients.
Subject: Subject from the original message
Sent: MM/DD/YYYY Time
The following recipient(s) could not be reached:
Recipient Email Address on MM/DD/YYYY Time
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<Host name="" that="" rejected="" the="" message="" #5.5.0="" SMTP=""; 554="" Recipient="" Email="" Address="" >: Relay access denied>
Example 2:
From: MAILER-DAEMON [MAILER-DAEMON]
Sent: Day, Month Date, Year Time
To: Sender Email Address
Subject: Undelivered Mail Returned to Sender
This is the Postfix program at host Server that rejected the message.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to <postmaster>
If you do so, please include this problem report. You can delete your own text from the attached returned message.
