Requirements
IPBan free version requires .NET 8 SDK to build and debug code. For an IDE, I suggest Visual Studio Community for Windows, or VS code for Linux. All are free. You can build a self contained executable to eliminate the need for dotnet core on the server machine, or just download the precompiled binaries in releases.
Running and/or debugging code requires that you run your IDE or terminal as administrator or root.
Officially supported platforms:
Windows 10 or newer (x86, x64)
Windows Server 2016 or newer (x86, x64)
Linux Ubuntu x64 (requires firewalld)
Linux Debian x64 (requires firewalld)
Linux CentOS x64 (requires firewalld)
Linux RedHat x64 (requires firewalld)
Mac OS X not supported at this time

Features
Auto ban ip addresses by detecting failed logins from event viewer and/or log files. On Linux, SSH is watched by default. On Windows, RDP, OpenSSH, VNC, MySQL, SQL Server, Exchange, SmarterMail, MailEnable are watched. More applications can easily be added via config file.
Additional recipes for event viewer and log files are here: https://github.com/DigitalRuby/IPBan/tree/master/Recipes
Highly configurable, many options to determine failed login count threshold, time to ban, etc.
Make sure to check out the ipban.config file (formerly named DigitalRuby.IPBan.dll.config, see IPBanCore project) for configuration options, each option is documented with comments.
Banning happens basically instantly for event viewer. For log files, you can set how often it polls for changes.
Very fast - I’ve optimized and tuned this code since 2012. The bottleneck is pretty much always the firewall implementation, not this code.
Unban ip addresses easily by placing an unban.txt file into the service folder with each ip address on a line to unban.
Works with ipv4 and ipv6 on all platforms.
Please visit the wiki at https://github.com/DigitalRuby/IPBan/wiki for lots more documentation.

What Is Self-Hosting?
Self-hosted emails are the servers that can be hosted in your local network or your server. If you want, you can always use it by integrating with third-party email accounts. However, its primary function is to let you create your very own email server.

Mailu self-hosted email server
Users can easily use aliases, auto-forward, autoreply, and fetched accounts to save time and effort. Global admins, per-domain delegation, announcements, and quotas are some of its administrative attributes that will let you seamlessly manage this email server.

Moreover, the platform uses TLS, Letsencrypt! certificate, outgoing DKIM, greylisting, antivirus scanner, anti-spam, auto-learn, DMARC, and SPF to ensure maximum security.

3. Docker MailServer
Docker MailServer is an open-source and full-stack mail server that supports email service through SMTP, LDAP, and IMAP. This production-ready solution comes with only configuration files that keep it simple and versioned. The server has no SQL database and can be deployed and upgraded readily.

It also supports creating custom rules for SpamAssassin and ClamAV, including automatic updates. The server uses LetsEncrypt and self-signed certificates to ensure data security. Users also get features, like setup script for server configuration and maintenance, basic Sieve support through Dovecot, persistent data and state, and extension delimiters.

Your device should have 1 vCore and 512MB RAM to run this server. However, you should deactivate services like ClamAV to run on a host containing 512MB of RAM. For optimum performance, the recommended configuration includes 1 Core processor, 2GB RAM, and enabling swap for the container.

Configuring Nginx to Use your Error Pages

Now, we just need to tell Nginx that it should be utilizing these pages whenever the correct error conditions occur. Open the server block file in the /etc/nginx/sites-enabled directory that you wish to configure. We will use the default server block file called default, but you should adjust your own server blocks if you’re using a non-default file:

sudo nano /etc/nginx/sites-enabled/default

Direct 404 Errors to the Custom 404 Page

Use the error_page directive so that when a 404 error occurs (when a requested file is not found), the custom page you created is served. We will create a location block for the file, where we are able to ensure that the root matches our file system location and that the file is only accessible through internal Nginx redirects (not requestable directly by clients):

/etc/nginx/sites-enabled/default

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        . . .

        error_page 404 /custom_404.html;
        location = /custom_404.html {
                root /usr/share/nginx/html;
                internal;
        }
}
