DNHAT Advanced Settings -  marketplace email configuration

Sample Email Settings for GMail accounts
DNHAT Settings, Configuration for Gmail email accounts
Users Accounts
You may want to set options for new users to go through the registration process before they can buy or sell on your platform.

Remember, you marketplace powered by DNHAT  is not just domain landing pages, but comes with all necessary tools to  receive offers for your domains, carry out negotiations,  communicate with advanced messaging system with unlimited number of buyers for your domains. In addition to that, you have the option to allow or disallow buyers' to register an account before they can place/send offers for your domains.

Settings available to limit access for users are:
Allow Registration - Yes/No;
Force Buyer Registration - Yes/No;

Be careful with forced registration. If you insist on registration, some potential buyers may abandon the registration form and leave altogether.
Form spams are serious security issues for site owners. Spam bots prowl the web, locate forms, fill in "garbage" and submit. And there a robots that input malicious codes in order to exploit your server security vulnerabilities.

An easy-to-implement but not fool-proof (especially on "specific" attacks) solution is enabling anti-spam captchas, blocking multiple submission from same IP within a given time interval or/and blocking the IP entirely. These are the minimum requirements:
Use captcha codes to protect forms from spam robots submissions - Yes/No;
Block form submission from same IP after X number of repeated/failed submissions - 3;
Block IP for Max time (in seconds) before next trial - 30;

Because CAPTCHA / reCAPTCHA doesn't currently stop bot form submission, DNHat has additional built-in anti-spam mechanism, strong enough to weed out 99% of fake form submissions and mitigate attacks. This includes, but not limited to:
- IP blacklisting
- Form field values analyses for suspicious patterns
- Rate Limiter
- Threshold-time comparison
