Informationwave Blacklist Removed

We received reports last night that the RBL (Real Time Blacklists) InformationWave went down. We have removed it from our database and no more alerts should be received.

The Informationwave was an open relay data base which listed open relays which has recently closed its doors. Most RBLS (Real Time Blacklists)
when they wish to dissolve will commonly blacklist the entire internet
in order to get the attention of those people using them to stop
attempting to contact their IPs.

MxToolBox is not affiliated with any Blacklists, we just provide a public tool that can be utilized to see if you are on a Blacklist. If you are on a Blacklist, rest assured as we do offer Blacklist Protection! For more information please feel free to visit our website or email us at

We’re always looking for new Blacklists to add, so if you want to suggest one to us, please send an email to
