Our IP address was recently added to CBL (blocklist/blacklist) for reasons we cannot fathom and that they haven't made at all clear (and apparently will not-- there is no way to contact them, seek due process, assert innocence until proven guilty or any such quaint historical nonsense). Their web site claims that they only list "compromised" systems (viruses/open proxies), but we're running a very tight firewall with CentOS 5 -- a standalone server at Slicehost.com that does no address translation for any other machines (a common way that compromised systems are masked).
I suspect the problem may have something to do with our domain name not matching our e-mail addresses (we receive our e-mail through a 3rd party service) or some other configuration "problem".
http://cbl.abuseat.org/namingproblems.html describes CBL's criteria for RFC-compliant HELO responses and I suspect that's where we've run afoul of their detection scheme, but this is rather out of my field and so I am seeking help/consulting to understand and resolve the problem. This is an urgent problem since email to our online store customers confirming their orders is probably not being delivered, thus, a rapid turn around will be most valuable to us.
