WPProAtoZ Email & IP Guardian

Contributors: WPProAtoZ.com Tags: email, wp_mail, disable email, ip restriction, admin notice, development, cidr Requires at least: 6.0 Tested up to: 6.7.2 Stable tag: 1.9.2 Requires PHP: 8.0 License: GPLv2 or later License URI: https://www.gnu.org/licenses/gpl-2.0.html A lightweight plugin to toggle outgoing WordPress emails and restrict site access by IP, perfect for development and testing environments.

Description

WPProAtoZ Email & IP Guardian is a lightweight plugin designed for developers and site administrators who need to manage outgoing emails and site access in WordPress. With a simple settings page under "Settings" > "IP & Email Controls", you can disable all emails sent via wp_mail() and restrict site access to specific IPs or IP ranges using .htaccess. Ideal for development, staging, or testing environments, this plugin prevents unwanted emails and unauthorized access with minimal configuration.

Key features:

• Disable all outgoing emails with a single checkbox.
• Customize the admin notice displayed when emails are disabled (default: "THIS DEV SITE HAS NO OUTGOING MAIL Mail from wp_mail() has been disabled for this site.").
• Log blocked emails to debug.log when WP_DEBUG is enabled.
• Test email functionality with a built-in button.
• Restrict site access to allowed IPs or IP ranges via .htaccess.
• Dynamic IP management with add/remove functionality and optional notes.
• CIDR notation support (e.g., 192.168.1.0/24).
• Uses both wp_mail filter and phpmailer_init fallback for reliable email blocking.
• Documentation tab for easy updates via external HTML file.

No need to edit core files or wp-config.php—everything is managed through an intuitive settings page.

Installation

1. Upload the wpproatoz-email-ip-guardian folder to the /wp-content/plugins/ directory, or install the plugin directly through the WordPress plugins screen.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Navigate to Settings > IP & Email Controls to configure the plugin.

Usage

1. Go to Settings > IP & Email Controls in your WordPress admin dashboard.
2. Email Settings:
   • Check "Disable Outgoing Emails" and save to stop all emails. A customizable admin notice will appear.
   • Adjust the "Custom Notice Text" field (optional) and "Notice Background Color".
   • Enable "Log Blocked Emails" to track blocked emails in debug.log (requires WP_DEBUG).
   • Click "Send Test Email" to test email functionality.
3. IP Restriction Settings:
   • Check "Enable IP Restriction" to limit site access to listed IPs. Your current IP is auto-added.
   • Add or remove IPs/ranges/CIDRs (e.g., 192.168.1.1-192.168.1.10 or 192.168.1.0/24) in the "Allowed IPs" section, with optional notes.
   • Save changes to update .htaccess.
4. To revert, uncheck the respective options and save.
5. Switch to the Documentation tab for guides and updates (loads from documentation.html in the plugin directory).

Tested with common email triggers (e.g., password resets, registrations) and IP restrictions on Apache servers.

Frequently Asked Questions

Why would I want to disable outgoing emails?

Useful in development or staging environments to prevent test emails from reaching real users.

Can I customize the admin notice?

Yes, enter custom text and choose a background color in the settings. Defaults apply if left blank.

Does this block all emails?

Yes, it blocks all wp_mail() emails using a filter and phpmailer_init fallback for reliability.

What happens when emails are disabled?

Emails are silently blocked, and wp_mail() returns as if successful, avoiding plugin errors.

Can I see which emails were blocked?

Enable "Log Blocked Emails" to log details to debug.log (requires WP_DEBUG).

How does IP restriction work?

It writes rules to .htaccess to allow only specified IPs/ranges/CIDRs, blocking all others.

Does it support IP ranges or CIDR?

Yes, enter ranges like "192.168.1.1-192.168.1.10" or CIDRs like "192.168.1.0/24" in the Allowed IPs section.

What are IP notes for?

Optional labels (e.g., "Office VPN") to track what each IP is for—doesn't affect restrictions.

How do I update documentation?

Edit documentation.html in the plugin directory; changes load on page refresh.
