 I am trying to figure out how to block email domains. I get a lot of registrations from Russia and Poland. How can I do a wildcard on mail.ru or other domains used by spammers/hackers? Thank you.

The easiest way would be to use the GeoIP block feature. It blocks IP addresses that are registered to a particular country or region. Note that you need to install the plugin from our website if you haven't already. The country registrations are provided by a third party service. It is about 90% accurate, so you will still get Russian IPs that the service thinks are in a different country.

This works well if it is a script trying to register. It doesn't work so well against humans. A human will just log into a proxy server in an allowed country and continue on his or her merry way. Also note that if you have any legitimate Russian visitors, this is not an appropriate solution.

Have Geoblock on with all these countries as not valid, but that does not seem to work all the time. I use regular Joomla Registration. But Admin Tools allows emails to be blocked as well, but how does one block an email domain?

The email domains are under Web Application Firewall, Configure WAF, on the Joomla! Feature Hardening Options tab, in the bottom field enter one domain per line.

Dale I understand but I like to block for instance *@mail.ru but i do not know nor can find syntax needed for that. So not just complete email address but wildcard. Thanks

The wildcard you want is to black all users, right? You would simply enter the domain in the field, mail.ru. That blocks all users from that domain.

I have mail.ru in my list, but still entries come through how is this possible then?

This is what Nicholas suggested:

Admin Tools only blocks registrations done through Joomla! itself.

If you are registering a user through a third party extension such as Community Builder, JomSocial or Akeeba Subscriptions the protection does not apply.

In fact, it cannot work as we can neither hook into 3PD code nor does Joomla! let us hook on user record creation and ​prevent​ it from happening.

I use Joomla Registration on this site. So what am I doing wrong I wonder.

I don't hear anything that you're doing wrong. I'll have to get with Nicholas again. I don't expect to be able to talk to him before Monday. I'll let you know what I find out.
