Exchange Blacklist

[bsl1973]

We keep getting black listed on BACKSCATTERER. I have cleaned every PC in the building and I refuse to pay $101 to have it removed immediately. How do I get this removed? We have exchange 2007 on a Windows Server 2003. It is causing some emails that are being sent to not go out of the exchange que. Any help would be appreciated.

So if you enter your IP on the site, does it tell you any relevant info?

It just says I am listed.

I ran into this with my exchange 2010 implementation... One BL showed me on the list and other BL's showed me as okay.

which test are you running. I like MXtoolbox utility. the results showed I was BL on one single list. I wrote an email to them with a detailed explanation of who I was along with contact and a day later... our server was removed.

I would suggest looking at a couple things.

1. The send connectors EHLO advertisement, and if it matches up to your Reverse DNS record with your ISP
2. Do you have a reverse DNS record.
3. Do you have more than one static IP, if not then I would suggest you lock down outbound 25 to only the Exchange server so that you can localize the problem to being at the mail server and not some bot'd workstation blasting spam off that IP.

Even if you DO have more than one IP, you should block SMTP at the firewall except that coming from Exchange (caveat being that Exchange is the only thing that *should* be sending mail out).
