What are the potential conflicts between the mail function in XAMPP and Exchange servers, specifically related to port 25?

When using the mail function in XAMPP to send emails through an Exchange server, there may be conflicts related to port 25 being blocked or restricted by the Exchange server. To solve this issue, you can configure XAMPP to use a different port for sending emails, such as port 587 which is commonly used for secure email transmission. 

// Set the SMTP port to 587
ini_set('smtp_port', 587);

// Send email using XAMPP mail function
mail('recipient@example.com', 'Subject', 'Message', 'From: sender@example.com');
