Email error codes linked to data volume with Mail Pro: LPR-SIZEXX

Procédure

Introduction

Welcome to our documentation dedicated to resolving the errors obtained when sending emails with a large volume of data from 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-SIZEXX type errors

LPR-SIZEXX type errors occur when our system detects that one or more professional email addresses have sent emails with too large a volume of data 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 hack on a device or website where the email address is configured. If mass e-mails contain large attachments, the system may block them. To solve this problem, it is essential to understand its origin and to take appropriate measures.

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

This blocking is applied to enable our system to absorb the load, to prevent excessive use of bandwidth and to temporise the voluminous sending flows which are often the consequence of abnormal use of the email service.

The system calculates the volume of data 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 e-mails sent, the effective blocking time will generally be much reduced.

III. Unblocking Your Mail Service

A. Unblocking the LPR-SIZE00 error

The LPR-SIZE00 error is not blocked for any length of time. All you have to do is resend the e-mail, making sure that the total volume of data does not exceed the authorised limit for your e-mail address.

B. Unblocking LPR-SIZE01, LPR-SIZE03, LPR-SIZE11 and LPR-SIZE13 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 the large volume of data being sent in order to prevent any further blocking.

C. Unblocking LPR-SIZE02 and LPR-SIZE12 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 the large volume of data being sent in order to prevent any further blocking.

IV. Preventing LPR-SIZEXX type errors

If you are the source of the large volume of data being sent by e-mail :

If this blockage occurs after you have sent a large volume of data by e-mail such as a newsletter or canvassing, we recommend that you set up time delays when sending the data in order to make them more fluid and to space them out over time.

If you do not wish to extend the time taken to send emails, we suggest that you use the services of companies specialising in this type of sending, such as MailJet or SendinBlue.

If your emails contain large attachments, we recommend that you host these attachments on your LWS hosting or on a data-sharing system and only include a download link in the email so that the recipient can retrieve the content.

If you are not responsible for sending large volumes of data by e-mail :

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.
