SMTP settings must be configured to send emails. Otherwise you cannot use features and modules that use the SMTP system.

The SMTP settings page allows you to configure the parameters necessary for your email sending functionality. Below are the input fields with brief explanations of their purposes:

  • SMTP Server: Enter the address of your SMTP (Simple Mail Transfer Protocol) server. This is the server responsible for sending your emails.

  • SMTP Port: Specify the port number used by your SMTP server. Common values include 25, 587, and 465, depending on the security configuration.

  • SMTP Security (SSL/TLS): Choose the security protocol for your SMTP connection. Options include SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to encrypt the communication between your server and the SMTP server.

  • SMTP E-Mail: Provide the email address associated with the SMTP server. This is typically the address from which your system will send emails.

  • SMTP E-Mail Password: Enter the password associated with the SMTP email address. This ensures secure access to the SMTP server for sending emails.

  • Ensure the accuracy of these settings to enable seamless communication with your SMTP server for effective email delivery.
