Feature
Domain MX checks — Optionally checks if the email domain has valid MX records (cached) to detect obviously fake addresses.
How it works
If enabled, AegisSpamGuard performs a DNS lookup and caches results so the check is fast after the first run. Failed MX can add points or trigger Challenge/Hold depending on policy.
How to access / enable
- WP Admin → AegisSpamGuard → Settings
- Identity module settings
- Toggle “Enable MX checks” ON/OFF.
Recommended setting
Recommended: OFF on shared hosting unless you verify DNS performance; enable after testing.
DNS lookups can be slow or blocked in some environments—test first to avoid latency.
Why you need this
Admins who rely on email deliverability and quality can use this to reduce fake signups.
