The IP of my server is blacklisted , so if i send email to gmail it gets blocked. The reason is comment email-forwarding of spam comments in a WP instance. I cant do anything about this.
This gives me problems when registering new users. I cant really register new users if the verification is via email. I can disable email verification but then i get into the next problem: Spam bots, and i got three after 24 hours of experimenting with ASMBB.
Therefore it would be nice to have some hidden email field with a fixed value like "firstname.lastname@example.org" and a check of the value when email verification is deactivated. If it's tampered with and email verification is deactived then it's a nonhuman user.
