1. Check on blacklists: You can check whether your domain name is listed on popular blacklists such as Spamhaus, Barracuda or SURBL by searching them directly on their websites. These services maintain a list of IP addresses and domain names that are known to send spam, malware or engage in other malicious activities.

1. Test email delivery: Send an email from your domain to a test email address. If the email is delivered successfully, your domain is not blacklisted. If it gets rejected or flagged as spam, it is likely that your domain is blacklisted.

1. Use online tools: Several online tools are available that can check the reputation of your domain name. These tools scan several blacklists and other databases to determine if your domain is blacklisted.

1. Use command-line tools: You can also use command-line tools like dig and nslookup to check whether your domain is blacklisted. By querying DNS records, you can determine whether your domain has been flagged as malicious by security services.
