Tempmails vs Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Addon Ecosystem Tempmails Core is frozen infrastructure. All new functionality is delivered via addons using a documented, stable hook system — your site never breaks on Core updates. Available addon hooks cover: email generation, message routing, inbox access control, multi-domain support, billing integration, and more. See the Hooks section below for the full reference. Privacy Tempmails stores temporary email addresses in browser cookies to maintain inbox sessions between page loads. No personal data is collected, stored against user accounts, or transmitted to any external service. See External Services below for details on the optional GitHub ecosystem feed. Hooks Tempmails exposes a complete hook system for addon developers. All hooks below are stable and frozen — they will not be renamed, removed, or have their signatures changed in any minor version.

What this connection does: Fires only when viewing Tempmails admin pages Retrieves only public, non-personal JSON content Transmits no user data, site URL, or any identifiable information Results are cached locally for 1 hour to minimize requests Remote endpoint: https://raw.githubusercontent.com/ubermensch-site/tempmails-ecosystem/main/ecosystem.json Service provider: GitHub Privacy policy: https://docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement To disable this connection entirely, uncheck Ecosystem Feed under Tempmails → Settings → General. Hardcoded fallback content is shown instead — no requests are made. Google Fonts The frontend inbox loads the Inter and Poppins typefaces and the Material Symbols icon font from Google Fonts CDN. What this connection does: Fires only on pages where [tempmails_inbox] is rendered Transmits the visitor’s IP address to Google as part of a standard font request Service provider: Google Fonts Privacy policy: https://developers.google.com/fonts/faq/privacy To avoid this (e.g. for GDPR compliance), dequeue tempmails-google-fonts and load self-hosted font copies instead. Developers This section documents internal implementation details, security practices, and notes for addon developers. Security Hardening Log All security changes are tracked here for auditing purposes. 2026-04-04 — Security Review Pass (v1.0.7 patch) class-core.php — ajax_delete_message(): $_POST['message_id'] was wp_unslash()-ed but not sanitized, with a phpcs:ignore suppression comment masking the warning. Now wrapped with sanitize_text_field( wp_unslash( … ) ). Suppression comment removed. 2026-04-02 — Security Review Pass (v1.0.7 patch) class-design.php — Removed raw echo from render_page(). Static CSS moved to assets/css/admin.css. class-design.php — inject_css_variables() refactored: replaced echo “…” with wp_add_inline_style('tempmails-admin', ...). All $v() return values now pass through esc_attr(). class-design.php — inject_frontend_css_variables() refactored: all CSS values escaped with esc_attr(), wp_strip_all_tags() applied. class-design.php — wp_footer fallback replaced raw echo ' ' with a dummy registered style handle. class-tempmails-shortcodes.php — Inline replaced with wp_add_inline_script(‘tempmails-frontend’, …). class-ecosystem.php — Inline replaced with wp_add_inline_script(‘tempmails-admin’, …). class-core.php — ajax_mark_seen(): sanitized with sanitize_text_field( wp_unslash( … ) ). class-admin.php — save_settings(): Raw $_POST replaced with $clean_post = array_map(‘sanitize_text_field’, wp_unslash($_POST)). class-email-generator.php — get_emails(): Cookie data sanitized with array_values(array_filter(array_map('sanitize_email', $raw))). Addon Development Notes Hook Stability Guarantee All hooks listed in the == Hooks == section are frozen. Signatures will not change in any 1.x release. Breaking changes will only occur in a major version bump with a migration guide. $clean_post in save_settings hooks As of the 2026-04-02 security patch, both tempmails_before_save_settings and tempmails_before_save_imap_settings receive a sanitized copy of $_POST. If your addon previously relied on raw values via these hooks, retrieve those fields directly from $_POST with appropriate sanitization. CSS Variable Injection inject_css_variables() now attaches inline CSS to the `tempmails-admin` style handle. If your addon dequeues tempmails-admin, Design color variables will not be applied on admin pages. inject_frontend_css_variables() uses a priority waterfall: 1. Attaches to tempmails-frontend if registered/enqueued 2. Falls back to tempmails-frontend-css 3. Registers a dummy handle tempmails-design-vars in wp_footer at priority 1 File Structure tempmails/ ├── assets/ │ ├── css/ │ │ ├── admin.css │ │ ├── frontend.css │ │ └── ecosystem.css │ └── js/ │ ├── admin.js │ ├── admin-design.js │ └── frontend.js ├── core/ │ ├── class-core.php │ ├── class-admin.php │ ├── class-design.php │ ├── class-ecosystem.php │ ├── class-email-generator.php │ └── class-addon-handler.php ├── includes/ │ ├── class-tempmails-shortcodes.php │ ├── class-tempmails-database.php │ ├── class-tempmails-settings.php │ ├── class-tempmails-imap.php │ └── class-tempmails-fetcher.php └── tempmails.php
