This guide assumes you have a functioning MediaWiki 1.40 installation and access to its configuration files. Understanding Web Server Configuration is also beneficial.
Overview
Email configuration in MediaWiki involves setting up the software to interface with a Mail Transfer Agent (MTA) – a service responsible for sending emails. Historically, MediaWiki could send emails directly using PHP's `mail()` function. However, this method is increasingly unreliable due to spam filtering and deliverability issues. Modern best practices advocate using a dedicated SMTP (Simple Mail Transfer Protocol) server. SMTP provides a more secure and reliable method of sending emails, offering features like authentication and encryption. Choosing the right method depends on your hosting environment, technical expertise, and the volume of emails your wiki generates. Incorrectly configured email settings can lead to users not receiving registration emails, password reset links, or important notifications, severely impacting usability. Additionally, failures in email delivery can affect features relying on email verification, such as User Rights Management.
The key configuration parameters are located in the `LocalSettings.php` file of your MediaWiki installation. These include specifying the SMTP server address, port, username, password, and encryption method. We will delve into each of these parameters in detail. Understanding PHP Configuration is also helpful as MediaWiki relies heavily on PHP.
Specifications
The requirements for email configuration depend heavily on the chosen method (direct `mail()` function or SMTP). However, certain specifications are universally important. Below is a detailed breakdown of these specifications, focusing on SMTP as the recommended method. The table also explicitly mentions "Email Configuration in MediaWiki" for clarity.

| **`$wgSMTPEncryption`** | The SMTP encryption method. | tls | Critical |
| **Email Configuration in MediaWiki** | The topic of this configuration | N/A | Informational |
The above table shows the essential specifications. Further requirements include a properly configured DNS record for your domain, allowing for SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records to improve email deliverability. A well-configured DNS Server is vital for this. Consider using a dedicated email deliverability service if you anticipate high email volume. This impacts the resources used by your **server**.
Use Cases
Email configuration in MediaWiki supports a wide range of use cases, all contributing to a functional and engaging wiki experience.
- **User Registration:** New users require email verification to activate their accounts.
- **Password Reset:** Users can request a password reset link via email.
- **Notifications:** Users can receive notifications about changes to watched pages, mentions, or other events. Notifications System
- **Email User:** Administrators can use the "Email this user" feature to directly communicate with registered users.
- **Special:EmailForm:** Allows users to send email to other users directly from the wiki.
- **Spam Prevention:** Email verification helps prevent the creation of spam accounts.
- **Moderation Alerts:** Administrators can receive email alerts about flagged content or user activity.
- **Automated Reports:** Running reports or statistics can be automated to be delivered via email.
- **SMTP Server Performance:** The performance of your chosen SMTP server is the most significant factor. A slow or overloaded SMTP server will inevitably result in slow email delivery.
- **Network Latency:** The network connection between your MediaWiki server and the SMTP server affects delivery speed.
- **Email Size and Complexity:** Larger and more complex emails (e.g., those with HTML formatting or attachments) take longer to send.
- **PHP Configuration:** PHP settings, such as memory limits and execution time, can affect the performance of email sending scripts. PHP Optimization is key.
- **MediaWiki Caching:** Caching mechanisms in MediaWiki can help reduce the load on the server and improve overall performance, including email sending.

These use cases are crucial for maintaining a vibrant and secure wiki community. A dedicated **server** with sufficient resources is essential for handling these processes efficiently, especially in larger wikis. Consider the impact on Server Load Balancing when planning for high email volume.
Performance
Email sending performance directly impacts the user experience. Slow email delivery can lead to frustration and abandoned account creation attempts. Several factors influence performance:
Below is a table outlining performance metrics to monitor:
| Metric | Description | Target Value | Monitoring Tool |
|---|
| **Email Delivery Time** | The time it takes for an email to be delivered to the recipient. | < 2 seconds | Server Logs, Email Monitoring Services |
| **SMTP Server Response Time** | The time it takes for the SMTP server to respond to a connection request. | < 0.5 seconds | Network Monitoring Tools |
| **Email Queue Length** | The number of emails waiting to be sent. | < 10 | Server Logs, Job Queue Monitoring |
| **Server CPU Usage** | CPU utilization during email sending. | < 70% | Server Monitoring Tools |
