Fighting Recruiter Spam with PHP - Proof of Concept

This article details building a custom PHP email processor to manage recruiter spam. It leverages the Fetch library for IMAP interaction and SwiftMailer for automated replies. A scoring system based on keywords and sender information identifies spam, allowing for automated responses or deletion. The tutorial addresses potential reply loops and false positives. Future improvements include a multi-user application, enhanced rule engine, and machine learning integration.

Key Features:

• Customizable Spam Rules: Define rules based on keywords, sender domains, and other criteria to identify recruiter spam with a points-based system.
• Automated Responses: Automatically reply to identified spam with a customizable template, deterring further unwanted emails.
• IMAP Integration: Seamlessly integrates with IMAP mailboxes (Gmail, FastMail, etc.) to retrieve and process emails.
• Folder Management: Organizes processed emails by moving them to a designated folder ("autoreplied").
• Whitelisting: Prevents reply loops and false positives by identifying and excluding emails containing specific identifiers.

The author highlights the inadequacy of built-in spam filters in modern email providers, motivating the need for a custom solution. The tutorial steps through setting up a development environment using Homestead Improved, installing necessary libraries (Fetch and SwiftMailer), and connecting to Gmail and FastMail accounts using app passwords.

The core functionality involves fetching unread emails, applying predefined rules to score them as recruiter spam, and then automatically replying and moving them to a designated folder. The code examples demonstrate how to:

• Fetch unread emails using $server->search('UNSEEN');
• Implement a scoring system to identify recruiter spam.
• Use SwiftMailer to send automated replies.
• Mark emails as read and move them to a specified folder.

The article concludes by outlining future development steps, including:

• Creating a multi-user application with a database for rule management.
• Implementing a more sophisticated rule engine.
• Integrating machine learning for improved spam detection.
• Adding caching for performance improvements.
