[PERSON_NAME] on LWS email error codes

Procédure

When sending an email fails, an error message may be displayed or returned to you by email. This message often contains an error code that quickly identifies the cause of the problem.

This help allows you to find the appropriate documentation according to the code displayed. [PERSON_NAME] not each error: each family of codes has specific help with explanations and actions to take.

Before you start

Before looking for the solution, retrieve the full error message. It may appear:

• in the return email received after a failed send;
• in your email client;
• in your Webmail;
• in the LWS interface if the block concerns a website or a PHP script.

The most important thing is to identify the exact code indicated in the message: for example L-RATE, L-RCPT, L-SIZE, L-SPAM, L-IP, MAIL, LPI or even an SMTP code like 550.

Find the help corresponding to your error code

Use the table [PERSON_NAME] consult the appropriate help.

I do not recognize the sends indicated in the error

If the error message indicates a large number of sends even though you sent nothing, it may be:

• a compromised email address password;
• an email client configured on a device you no longer use;
• a website that sends too many emails;
• a contact form being exploited to send spam;
• a script installed on your hosting.

In this case, start by:

1. Changing the password of the affected email address.
2. Updating this password in your email clients.
3. Checking the devices connected to this address.
4. Reviewing the contact forms or sending scripts present on your website.
5. Consulting the help corresponding to the error code displayed.

How can I check that the problem is solved?

After applying [PERSON_NAME] corresponding to your error code, perform a new test send.

The problem is usually solved if:

• the email is sent correctly;
• you no longer receive a return error message;
• the same error code does not appear again;
• the block does not return after a few more sends.

Common issues

I cannot find the error code in the message received

Re-read the full message, especially the lines containing terms such as error, blocked, rejected, SMTP, L-RATE, L-SPAM, 550 or 451.

If no LWS code is visible, it may be a standard SMTP error. In this case, consult the help: Understanding the main email error codes and their meaning.

The block should have disappeared, but sending still fails

Some blocks require a delay before being lifted. [PERSON_NAME], the block may be extended or happen again.

Also check that the cause has indeed been fixed: [ADDRESS], attachment size, invalid addresses, compromised password, or overly active sending script.

The error concerns my website and not my mailbox

If the error appears when sending from a contact form, an online store, WordPress, Prestashop, or a PHP script, consult instead the help related to the codes LPI, LPB, LPO or to the PHP function mail().

In this case, the problem does not necessarily come from your email address, [ADDRESS] website or the script [PERSON_NAME] messages.
