According to the test on Backscatter.org About 3 times year we get blacklisted on backscatter.org. If we get blacklisted, Does that mean certain senders will not be able to send to us? I have only one customer that cannot deliver mail to our system. He claims this is why. I want to make sure I understand this. Also, Below are the test results I ran from Backscatter.org test/remove tool. I really dont understand what it all means or how to fix our problem....These IP addresses all point to www.timeanddate.com
This IP IS CURRENTLY LISTED in our Database.
Please note that this listing does NOT mean you are a spammer, it means your mailsystem is either poorly configured or it is using abusive techniques.
This kind of abuse is known as BACKSCATTER (Misdirected Bounces or Misdirected Autoresponders or Sender Callouts). Click the links above to get clue how and why to stop that kind of abuse.
To track down what happened investigate your smtplogs near 20.03.2012 11:44 CET +/-1 minute.
You will either find that your system tried to send misdirected bounces or misdirected autoresponders to claimed but in reality faked senders, or your system tried sender verify callouts against our members near that time.
So you should look for outgoing emails that have a NULL SENDER or POSTMASTER in MAIL FROM.
Reading your logs carefully it shouldn't be a big deal to figure out what caused or renewed your listing.
