IP block list download is the process of removing an IP address from an internet blocklist, which is used to prevent malware and spam attacks on devices that send such communications. Having an IP address in one of these lists can be damaging to email deliverability, so if you’ve been blocked, it’s important to know how to get de-listed as quickly as possible.

Getting added to an IP blocklist is usually due to being involved in suspicious activities such as spamming, hacking, and DDoS attacks. However, there are some other reasons why your IP may be blocked as well. For example, consistently sending emails with low engagement or poor quality can annoy subscribers, leading them to mark your messages as spam. This will irritate the ISP, which can lead to your IP being blacklisted.
To get your IP removed from the list, follow the directions on the site where you’re listed. Most will provide information on how to resolve the issue and ask you to take certain steps, such as correcting forward and reverse DNS records, setting SMTP banners, scanning network computers for viruses, updating routers, and establishing stronger passwords.
The most common way to block your PBX from hackers and malicious activity is to join the Yeastar Global Anti-hacking IP Blocklist Program, which is free for all Yeastar users. By enabling this option, any connections to your PBX from the listed IP addresses will be dropped, significantly reducing the risk of cyber attacks.
