What are some common pitfalls when configuring a web server for email functionality using xampp?

One common pitfall when configuring a web server for email functionality using XAMPP is not properly setting up the SMTP server settings in the php.ini file. To solve this issue, ensure that the SMTP settings are correctly configured with the appropriate host, port, username, and password.

// Set the SMTP server settings in php.ini
ini_set("SMTP", "your_smtp_host");
ini_set("smtp_port", "your_smtp_port");
ini_set("sendmail_from", "your_email_address");
