Source-destination mail Pro error codes: LPR-DSDRXX or LPR-DESTXX

Procédure

Introduction

Welcome to our documentation dedicated to resolving errors caused by sending a large volume of email from a single sender to a single recipient 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-DSDRXX and LPR-DESTXX errors

LPR-DSDRXX type errors occur when our system detects that a large number of emails have been sent from email addresses in the same domain to email addresses in the same domain that are different from the sending domain.

LPR-DESTXX errors occur when our system detects that a large number of emails have been sent to the same destination email address.

To solve this problem, it is essential to understand its origin and to take appropriate measures.

II. Quotas and blocking times for LPR-DSDRXX and LPR-DESTXX errors

This block is applied to prevent unsolicited mass mailings to the same recipient. Large volumes of emails sent to the same recipient are often the result of abnormal use of the email service.

The system calculates the number of emails sent to the same recipient 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 the same recipient, the effective blocking time will generally be much reduced.

III. Unblocking your Mail Service

You do not need to take any action to unblock a message sent from your email address(es) to the recipient concerned. It will automatically be reactivated after the blocking period.

However, it is advisable to find and resolve the source of this mass mailing to numerous recipients in order to prevent any further blocking.

IV. Preventing LPR-DSDRXX and LPR-DESTXX errors

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

If this block occurs after you have sent a large number of emails to the same recipient, please check the reasons for this mass mailing. The limitations proposed correspond to a quota which, if exceeded, would not allow the recipient to correctly process the emails received. We invite you to check the reasons for this mass mailing and to restrict the number of mailings or to group the information together in the same email to limit the number of mailings. In the case of notifications, it may be a good idea to use a more efficient notification system. In general, users who receive too many notifications over a short period no longer take them into account after a certain time.

If you are not the source of the mass mailings :

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.
