How to Fix the 'Failed to Connect to Mailserver' Error When Using `php mail()` on localhost?

Troubleshooting the php mail() Function on localhost

The php mail() function facilitates email sending, but when employed on a localhost server, it may encounter a "Failed to connect to mailserver" error. This error indicates that no mailserver is configured to handle email delivery.

Solution:

To remedy this issue, you must configure a mailserver on your local machine. If you are utilizing a Windows operating system (often the case with WAMP users), consider setting up a Pegasus mailserver. Alternatively, leverage wrapper classes like SwiftMailer or PHPMailer to establish connections with external SMTP servers such as Gmail.

These wrapper classes offer greater adaptability and enhanced security. Even if you opt for the Pegasus mailserver solution, it is advisable to employ these classes for their ease of use and improved features. Additionally, connecting to an SMTP server provided by your ISP or Gmail simplifies the process further.
