We have received reports that the RBL (Real Time Blacklists) ClueCentral has gone down. My Engineers have completed an investigation into the RBL and they discovered that stopped operating as of 1/21/2010. For more details of the site ceasing to operate, please view the Google Cache. At this time we have removed the Blacklist and our servers will be updated throughout the day to remove those alerts.
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 firstname.lastname@example.org.
For more information on what Blacklists are and how MxToolBox can help, read this blog post. We’re always looking for new Blacklists to add, so if you want to suggest one to us, please send an email to email@example.com.
