There are many different steps that are being taken in order to block spam from filling up our inboxes with unsolicited commercial e-mail. One of the most common measures taken is known as blacklisting (DNSBL). As part of our continued effort to fight SPAM at Pacific LANWorks, we have enabled DNSBL on your mail server. This is a process most commonly used by Internet Service Providers (ISPs), Domain Name Service (DNS) operators and network administrators which involves entering the IP address of known (or suspected) spammers into a network database. If a certain IP address is on the blacklist of an Internet Service Provider, for example, then we will automatically block any e-mails coming from the blacklisted IP address.
