Contact - Valid Email
Block spam in Joomla contact forms with the Contact - Valid Email plugin. This free tool validates email submissions in real-time, rejecting invalid formats, suspicious addresses, and non-MX domains while allowing legit ones. Features include MX record checks (cached for speed), email/domain whitelists & blacklists, MX provider blocking (e.g., Outlook protection servers), and silent mode for security. Integrates seamlessly with core forms. Ideal for clean inboxes on public sites.
