You might find Mailtrap useful for configuring email settings. Simply visit their website (https://mailtrap.io) and sign up. After signing up, you need to select Laravel 7.x and 8.x under integration then obtain your email server configuration keys. Copy the keys individually, one by one, and paste them into the Faculty LMS's server configuration under email settings. Please check the screenshot: https://prnt.sc/47MuNx8AVvXK
However, it's important to note that while Mailtrap is effective for testing and development, it may not be suitable for larger-scale usage due to limitations on user volume. So, while Mailtrap can be a great choice for testing and smaller projects, for larger-scale email needs, SendGrid or Amazon SES might still be more suitable options.
