Hello and welcome to another "special interest" post on MeAgainstTheWeb.de! Today, we'll discuss a crucial aspect of securing your mail server: blacklisting suspicious domains. By implementing this measure, you can prevent spam and other malicious activities from infiltrating your inbox.

Make your mail server a bit more secure by blacklisting the following domains. These domains are hand-picked by myself, and I block them in all mail server configurations. You are welcome to use it.

Suspicious Domains

Be aware: The first 4 lines are blocking all .cn, .cyou, .mk, and .ru domains.

About Blacklisting Domains

Now, you may be wondering why blacklisting these domains is necessary. Well, spammers and hackers often use these domains to send out malicious emails, phishing attempts, and other cyber threats. By blacklisting them, you're effectively blocking a large portion of potential threats and keeping your inbox clean and safe.

Here's how to add these domains to your mail server's blacklist:

• Access your mail server's control panel.
• Locate the blacklist or spam filtering settings.
• Add the domains from the list above to the blacklist.
• Save your changes and restart your mail server if necessary.
• Remember, this is just one step in securing your mail server. Always stay vigilant and keep an eye out for any suspicious activities or emails. It's essential to have strong security measures in place, such as using secure passwords, enabling two-factor authentication, and keeping your software up-to-date.

I hope you found this post helpful in securing your mail server against potential threats. You are welcome to share your thoughts, experiences, or additional tips in the comments section below. Stay safe, and happy emailing!
