Hi Tom,
If you are serious about blocking spam, take a good look at Fail2ban.
It is already installed on KeyHelp, and setup with some basic features to cover common usage. It is encouraged to make your own custom rules for fail2ban, to suit your purposes.
Fail2ban is very strong on blocking spam, especially with a little additional configuration. Searching this forum for "fail2ban" will yield plenty of good results, on how to add these configurations.
More configuration options are available too, with Postfix, Spamassassin, and Amavis, but as a novice I would focus on Fail2ban for now...

You can add blacklist server in KH. Also you can login into round cube and put the rule > if mail marked as ***SPAM*** > move it to trash or spam.

The software said: Requires Win Vista®, 7®, 8® or better. And so I installed Linux.
Re: fight spam
Of course, that is much easier... if not already done.
Re: fight spam
How to add blacklist in KH?
Also how to use Fail2ban for that? Any tutorial or example to block spammers using fail2ban?
Thanks.

Re: fight spam
Another question. What should I put in " DNS-based blacklists (DNSBL) "?
This is the place to put a *domain to block or a list of known blacklists?
How can I get those blacklists? Is necessary to subscribe to anything?
Would this be a list to use: https://en.wikipedia.org/wiki/Compariso ... blacklists ?
What are the most commom lists to put there?
Sorry, I'm new at KH. Thanks.

Blacklists are not a feature of keyhelp but of postfix. Please read the postfix manual, this is basic knowledge for an admin.
