RE: New DNS list for host information?
I'd agree it's useful - the more info the better - Did you already write a spamassassin plugin or are you saying someone needs to?

I'm considering a DNS list that would return strings as TXT records that contain key words that classify the Forward Confirmed rDNS name based on a number of flags. For example, if the host is yahoo.com it might contain yellow freemail indicating that it is yellow listed (mixed ham/spam) and that it is a freemail provider. Here's some tags I'm considering. black - blacklisted white - whitelisted yellow - mixed source nobl - nevr blacklist, but maybe whitelist freemail - fre mail service like yahoo, hotmail, gmail isp - isp consumer email servers - verizon, comcast etc. (mixed source) dynamic - end user dynamic IP range The idea being that there might be a number of different items that returns useful information to help process email. Exim is capable of processing these kind of conditionals. I'm not sure other MTAs are. SA could be modified to process it. Who likes this idea?
Re: New DNS list for host information?
I'm not saying anything positive or negative about the different lists, but there's a long precedent of doing this type of thing w/ bits in a standard DNS response. Look at SURBL and URIBL, for example -- a single response encodes multiple individual list entries, and there's no special code that needs to be written for it.
