Short answer: yes — you can send mail from a localhost development machine, but it requires either a properly configured local MTA (Postfix/Exim/msmtp/ssmtp) or an SMTP client library that authenticates to a remote SMTP relay. The post by is too absolute: PHP running on localhost can send mail, but not out-of-the-box in many environments without configuration. is pointing in the right direction: using SMTP with username/password is the common, reliable approach.

A practical, recommended workflow for development:

  • Use an SMTP library (PHPMailer, SwiftMailer) from PHP and point it at an authenticated SMTP relay (your host, Gmail with an app password, or a transactional service). This avoids having to run and secure a full MTA locally.
  • If you prefer a local MTA, install/configure Postfix or msmtp and set PHP’s sendmail_path (or SMTP settings on Windows) so mail() uses it.
  • For purely local testing without sending real mail, run MailHog or FakeSMTP to capture messages instead of sending them to the Internet.

Example (PHPMailer-style) SMTP setup:

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'user@example.com';
$mail->Password = 'app-password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

Troubleshooting tips: check /var/log/mail.log and PHP error logs, enable SMTP debug output in your library, test the SMTP connection with telnet/openssl s_client, and remember many ISPs block port 25 — use 587/465. For production, always use an authenticated relay and correct DNS (SPF/DKIM) because mail from a home IP is often marked spam or rejected.

References and quick starts: PHP mail() manual, PHPMailer examples, MailHog, Postfix. For a demo, the PHPMailer examples linked above show a minimal working script.
