Procédure

Introduction

Welcome to our documentation dedicated to resolving the errors obtained when sending emails to a large volume of recipients with professional email addresses and to managing the sending of emails on LWS. Here you will learn all about these errors and how to manage them effectively to avoid any unwanted blocking of your emails. Our aim is to provide you with clear and concise information to help you get the most out of your email service.

I. Understanding LPR-RCPTXX type errors

LPR-RCPTXX type errors occur when our system detects that one or more professional email addresses have sent emails to too many recipients compared to the limits set for their use.

This situation may arise as a result of a mailing list being sent from your email addresses, or as a result of a device or website where the email address is configured being hacked. To resolve this problem, it is essential to understand its origin and to take appropriate measures.

II. Quotas and blocking times for LPR-RCPTXX type errors

This block is applied to prevent the sending of unsolicited bulk email for which the owner of the email addresses is not responsible. Large volumes of email sent to a large number of recipients over a short period are often the result of abnormal use of the email service.

The system calculates the number of recipients present in the emails sent during the last reference period. The blocking time indicated in the table above is the maximum value, corresponding to a massive and rapid sending. If the blocking follows a regular flow of emails sent to different recipients, the effective blocking time will generally be much reduced.

III. Unblocking Your Mail Service

A. Unblocking LPR-RCPT01, LPR-RCPT03, LPR-RCPT11 and LPR-RCPT13 errors

No action is required to unblock the sending from your email address(es). It will be automatically reactivated after the blocking period.

However, it is important to find and resolve the source of this mass mailing to numerous recipients in order to prevent it from being blocked again.

B. Unblocking LPR-RCPT02 and LPR-RCPT12 errors

No action is required to unblock the sending from your email address. It will be automatically reactivated after the blocking period.

However, it is possible to unblock the IP address in advance by following this documentation.

However, you will need to find and resolve the source of this mass mailing to a large number of recipients in order to prevent any further blocking.

IV. Preventing LPR-RCPTXX type errors

If you are the source of the mass e-mailing :

If this blockage occurs as a result of you sending mass mailings to a large number of recipients, such as newsletters or canvassing, we recommend that you set up time delays during the mailings in order to make them more fluid and to space them out over time.

If you don't want to extend the time taken to send emails, we recommend that you use the services of companies specialising in this type of mailing, such as MailJet or SendinBlue.

If you are not the source of the mass emailing :

Run an anti-virus scan on the devices where your email addresses are configured. Use tools such as TotalAV, PCProtect, McAfee or Avast to remove all traces of viruses or malware. Then regularly change the passwords to your email accounts.

If your site sends emails with your email address, check that it is secure and that the forms have the Captcha function, which prevents robots from using your forms to send mass emails.

We have a number of documentations that explain how to set up this type of functionality on WordPress, Prestashop and Joomla sites.
