Que veut dire this is the mail system at host
A classic error message!
"This is the mail system at host" is a message that typically appears when your email client or a mail transfer agent (MTA) is unable to deliver an email to its intended recipient.
Here's what it usually means:
- The email client or MTA is trying to send an email to a recipient's email address.
- The email client or MTA is unable to find the recipient's email server or the server is not responding.
- The message is being sent back to the sender, indicating that the email cannot be delivered.
The "host" part of the message refers to the hostname or domain name of the email server that is supposed to receive the email. In other words, it's the name of the server that is supposed to handle the email delivery.
Common reasons for this error include:
- The recipient's email server is down or not responding.
- The recipient's email address is invalid or does not exist.
- The sender's email client or MTA is configured incorrectly.
- The email server is experiencing technical issues or is blocked by a firewall or spam filter.
To resolve this issue, you may need to:
- Check the recipient's email address for typos or errors.
- Verify that the recipient's email server is functioning correctly.
- Check your email client or MTA configuration to ensure it's set up correctly.
- Contact your email provider or IT support for assistance if the issue persists.
