    Need some basic insight here...

    OK - I have an exchange server behind our ISA Firewall and all of our IP addresses are natted.

    On rare occasion one of our emails get blocked and I am trying to figure out why. I have a sneaky suspicion is due to a listing on spews (see below)

    We have multiple domains such as internetseer.com, brandywine.com and a few more that we send out email from.

    Our external ip is

    on our dns servers and I have an A record setup for internetseer.com called : exchange.internetseer.com that resolves to

    for minddrivers I also have an A record called exchange.minddrivers.com that point to

    I also have reverse dns records setup for exchange.internetseer.com and exchange.minddrivers.com that resolve to

    one thing I discovered that annoys me is this: http://www.apews.org/?page=test&C=1403&E=383528&ip= - I don't know if this is important or not.

    The MX record for both internetseer.com and minddrivers.com point to mailcheck.internetseer.com which has an A record and also a reverse dns record and that points to which is our Spamtitan box located in a data center where we colo a number of our servers. The spam titan box forwards clean email to an ip I have defined to only listen to and the firewall forwards those smtp connections to our exchange server located behind the firewall.

    I 'd really like to get de-listed from spews but I don't understand what they're really indicating in their message.

    do any of you have any ideas?

    Search the page for "A42" to look at the section on getting removed. My personal opinion: There are a lot of sites that offer free spam filtering. Most are pretty poor and unprofessional. Read through their FAQ's and you'll see. Just my 2 cents.
