CM E-Mail Registration Blacklist Pro 1.6.3

CM E-Mail Registration Blacklist Pro is a WordPress plugin designed to reduce unwanted activity caused by spam registrations, comment abuse, and form submissions. It uses email-domain filtering to compare submitted email addresses against your blacklists and whitelist approvals. By blocking or permitting users based on the domain or email you define, it helps stop disposable email signups and other low-quality attempts before they reach your site. The result is a cleaner, more controlled user pipeline for WordPress sites that rely on registration, comments, or contact-style forms.

Main Features

• Blacklist filtering — Blocks registrations, comments, and form submissions using email domains or emails you add to your blacklist.
• Whitelist approval — Optionally allows only specific domains or emails through, rejecting everything else.
• Email-domain rules — Filters by domain patterns so you can target entire providers instead of single addresses.
• Registration protection — Prevents user signups that match blocked or unapproved email criteria.
• Comment spam reduction — Stops comment submissions from unwanted email domains or addresses.
• Form submission control — Applies the same filtering approach to emails submitted via site forms.
• Trusted domain management — Centralizes your approved and blocked entries to keep control consistent over time.
• Clear rule behavior — Uses blacklist/whitelist logic so admins can predict how requests will be handled.

Benefits

• Less junk signups — Reduces disposable and unwanted registrations by filtering emails at submission time.

• Better UX — Helps real visitors experience fewer friction points from rejected or abusive submissions.
