If you encounter an error when sending emails via SMTP: 



1. Download the latest version of the SMTP tool


  • Go to Parameters > General Options > Email tab.
  • Click the green download link to get the latest version of the tool.


  • Complete the download and install if necessary.


2. Adjust the delay configuration:

  • Navigate to the installation folder of LBRP / Belcofin.
  • Open the subfolder _Tools.
  • Locate the file SmtpLbrp.dll.config.
  • Open this file using a text editor (e.g., Notepad).
  • Find the following line: <add key="delay" value="0" />
  • Change the value to: <add key="delay" value="3000" />
    (This sets a delay of 3 seconds.)


3. Try sending again

  • Attempt to send the email again via SMTP.
  • If the error persists, gradually increase the delay value (e.g., to 5000 or 7000) until the issue is resolved.
