Is it a problem that my IP address is blacklisted by ZapBL?

ZapBL is a blacklist that is not being maintained by its owners or used as a blacklist service, so you don't need to worry if your IP address is blacklisted by ZapBL. Any information provided by this blacklist is severely outdated and irrelevant.

We're unable to give a clear answer to why your IP address was added to the ZapBL blacklist, but this blacklist is not used, so this does not affect you.
