Blacklist email domains

-- HikaShop version -- : 2.6.4

Hi there, we are getting orders from people with stolen credit cards. They are all using the same 3 email domains and we'd like to prevent anyone from being able to place an order with these specific domain names. Is there a way to do this within Hikashop or Joomla? Thank you very much!

Hi,

There are some security extensions for Joomla which allow you to block registrations from specific domain names.
I would recommend to check first Admin Tools and RS firewall.
