If you are searching for a suitable ISP for your business, it is a good idea to check if your IP address (or others hosted by this ISP) is listed on a DNS-based Blackhole list (DNSBL). The reason why you should do that is simple - if your ISP has given you an IP address which is listed, their mail server may also be on a blacklist and you may find yourself unable to reach your clients via e-mail. A simple test with our Test Tools will let you know if the domain name/IP address that you are testing is blacklisted. We query the major DNS Blacklists – Sorbs, Spamhaus, NJABL, DSBL, CBL and PSBL for specific IP address and return whether it is listed for sending spam, as an open proxy relay or for other possibly malicious activities. Check out the video below to see how this test works or give it a try now.
