Exchange Server 2010 R3. Windows Server 2008 R2.
I keep getting listed on BackScatterer.org. What must I do to configure my Exchange Server to prevent whatever is triggering this? I have not messed with any settings recently, nor do I really understand what backscatter is. I just want to configure properly to prevent blacklisting. Any help will be GREATLY appreciated. Thanks.
BackScatterer says,
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
27.04.2013 20:26 CEST+/-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.
