I am not sure that adding a reference to RFC 2505 to the history section would be a natural fit: that section is really just about the history of using reverse DNS as part of a security strategy. I think that anti-spam efforts are distinct from such a security strategy, so I think we should keep them separate. I can nevertheless see your argument, which is why I raised the topic in the meeting today. I did not hear much enthusiasm for the addition, but I think it's worth considering in light of your comment. Therefore, if people think it is a worthwhile addition, please send your comments to the list. If we want to make the addition, I propose that we add one sentence to a paragraph in section 3.1: Some anti-spam systems use the reverse tree to verify existing reverse mapping, or to check for matching reverse mapping. **This practice was encouraged by [RFC2505].** Some mail servers have the ability to perform such checks at the time of negotiation, and to reject mail from hosts that do not have matching reverse mappings for their hostnames. The new sentence is enclosed in asterisks. If anyone wants to speak strongly in favour of this addition, then we can decide whether we should proceed. In the absence of strong argument in its favour, I don't think we'll make the change, because my sense of the room today was that most people thought we should not add this.
