The 0spam Project
What if I'm listed?!
That really sucks, because removal from the 0spam project is not easy.
- First you need to verify that your sending Mail Server IP is currently listed with one of our DNSBL's.
- Next you will need to write down the "A Record" if you are listed.
- Now you need to see why you were listed, in many cases the TXT record shows why you were listed, sending server, date, subject of the spam
- Fix the problem, repeat offenders will have a two week removal wait on the second offence so fix the problem before proceeding with the removal process.
- Now use the form on the right to request removal, requests that do not follow the instructions on this page will be ignored. Seriously!

How does the 0spam service work?
Any time spam is sent to spam traps, an IP will be listed in the 0spam.fusionzero.com dnsbl with the data code of 127.0.0.#, when spam is sent from multiple IPs within a class C range to our spam traps the entire class C range will be listed with a 127.0.#.0 data code which is the maximum listing size.
