Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
My situation:
- High volume sites, using HONEYPOT + HIDDEN CAPTCHA + EMAIL_VERIFY leads to perfect protection against bots.
- Some bots are able to get through HONEYPOT + HIDDEN CAPTCHA, in those cases EMAIL_VERIFY is "the last stand".
- These bots are using similar e-mail address patterns, but constantly changing source IP.
Results:
- The e-mails servers start throttling and/or blocking SMTP and/or greylisting connections from my server.
Solution:
- Cache e-mail verification results for address proven to be "bad"
