However, this essential ability can be compromised for a variety of reasons. It is possible for malicious hackers to gain an unauthorised access to mailboxes or vulnerable websites to distribute spam.

The more spam gets released, the greater the likelihood the email addresses, your domain, or even the mail server of your ISP will be listed on a variety of IP blacklists.

What exactly does “blacklisted” mean?

Blacklists are usually comprised of email addresses or IP addresses that have been identified as being able to send spam. Numerous email hosting companies utilize these blacklists in public to aid in the effort to reduce the amount of email spam they receive through their network. They frequently conduct an IP blacklist search and block communication from IP addresses suspected of engaging in illegal actions. The blacklist includes a list with a variety of IP addresses which are blocked.

The aim of this is to safeguard the internet and other servers from attacks. This is accomplished by establishing rules within the server’s program or router hardware regarding what constitutes an attack, and then preventing machines from connecting to the traffic.

It’s not just emails that are sent to the inbox’s spam folder, but. When an IP address has been blocked, all emails are instead bounced back to the IP address until it has been removed from blacklist.

What causes blacklisting?

Being blacklisted can be initiated by a number of conditions. For instance, if a certain number of spam traps are triggered or mail is suspected to be received from a specific email or IP address within a specified period of time the email provider such as Google or Hotmail will discover the IP address from which it came from. In response they’ll block the IP address, and any emails sent to it will be rejected.

Because the spammer shares the hostname, and consequently the IP address of hundreds of innocent users could be placed on the blacklist and not able to send email through no cause or fault of their own. This is the reason it’s vital that the host is capable of preventing or swiftly rectify the issue and complete IP blacklist elimination as fast as it is possible.

For instance the compromise of a password for a mailbox or a web vulnerability caused by the failure to update an external WordPress application can result in the exploitation. Once hackers have done this, they are able to send emails for their own account, typically as an attack that is phishing. In most cases the user of the service is unaware that their service has been utilized to send out spam.

Marketing without knowledge

Another reason for IP address blacklisting occurs the case where a legitimate email marketer is wrongly classified as spammers. The majority mailers for marketing are classified as spam due to the fact that senders do not follow what is known as a ‘best practice’. Some examples of best practice are the inclusion of unsubscribe links in emails, or making sure that all subscribers are signed up using an ‘Confirmed Optimism Process’.

Professional spammers

However, the main reason for IP blacklisting happens is because of malicious actors who sign up to hosting services solely with the intention of using a platform for send spam. The goal is usually to send out emails that appear as if they come from a different organization or party to collect personal information, or to cause damage to other network networks by introducing malware or viruses.
