Introduction

Welcome to our documentation dedicated to resolving the errors obtained when sending emails to a large volume of recipients 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 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.

This documentation only concerns the quotas and error codes linked to the use of standard email addresses supplied with your hosting package. The same documentation exists for quotas and error codes relating to the use of professional email addresses

I. Understanding L-RCPTXX type errors

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

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

[tips_info] The limitations are not the same for the "standard" email addresses supplied with your hosting package and the professional email addresses offered by LWS[/tips].

This means that if one or more "standard" email addresses are blocked, the business email addresses attached to the domains can continue to send emails until they reach their own limits.

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

Error code	Error description	Reference period	Blocking time	Blocking target
L-RCPT01	emails to more than 600 recipients were sent from this email address during the reference period	1 hour	1 hour maximum	email address concerned only
L-RCPT02	devices using the same IP address sent emails to more than 2400 recipients from the domain's email addresses over the reference period	1 hour	1 hour maximum	IP address concerned only
L-RCPT03	emails to more than 2400 recipients were sent from your domain's email addresses during the reference period	1 hour	1 hour maximum	domain email addresses
L-RCPT11	emails to more than 6000 recipients were sent from this email address during the reference period	24 hours	24 hours maximum	email address concerned only
L-RCPT12	devices using the same IP address sent emails to more than 12,000 recipients from the domain's email addresses over the reference period	24 hours maximum	24 hours maximum	IP address concerned only
L-RCPT13	emails to more than 24,000 recipients were sent from your domain's email addresses during the reference period	24 hours	24 hours maximum	domain email addresses

This block is applied in order to prevent unsolicited mass mailings not originating from the owner of the email addresses. 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 L-RCPT01, L-RCPT03, L-RCPT11 and L-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, you should find and resolve the source of this mass mailing to numerous recipients in order to prevent any further blocking.

B. Unblocking L-RCPT02 and L-RCPT12 errors

No action is required to unblock the sending from your email address. It will automatically be 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 Type L-RCPTXX errors

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

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 duration of the emails you send, we recommend that you order one or more professional email addresses with higher quotas, or 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 e-mailing :

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.

Conclusion

We hope that this documentation has been useful in helping you to understand and resolve L-RCPTXX errors and to improve the management of your LWS mailings. By following the steps explained here, you can prevent unwanted blocking and optimise your email communication with your recipients. Don't forget to take security measures into account, in particular by changing your password regularly.
