We have received reports that the RBL (Real Time Blacklists) SATOS has gone down. My Engineers have completed some investigation and they discovered that the RBL SATOS isn’t dead, but their website is offline. Please see the Google Cache for more details.
However, in the mean time, we are not able to get reliable results from rbl.cluecentral.net so it has been disabled it for now.
For more information on what Blacklists are and how MxToolBox can help, read this blog post.
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.
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.
For information about other Blacklists that have shut down or Blacklists that are having problems, view this forum post.
