Fixing a Broken Contact Form That Stopped Sending Messages

Project context

A business website stopped receiving messages from its contact form.

Visitors could submit the form, but the company never received the emails.

This created a risk of missing potential customers.

Goal

The goal was to identify why the form submissions were not being delivered and restore normal operation.

Solution

The debugging process began with testing the full submission flow.

Logs revealed that form data was being processed correctly but email delivery was failing due to a server mail configuration change.

The fix involved adjusting the email transport configuration and verifying message delivery through SMTP.

Result

Form submissions were restored within one hour, and all messages began arriving correctly again.
