This is something of a thought experiment on what would have to be available for a Verisign or the like to make unilateral changes without presenting the idea for comment, well in advance. The process of asking for comment through IETF and the operational forums has the proven benefit of getting major players to look at the issue and decide to comment. Now, as you point out, there are many people who run mail servers and the like, who don't follow any relevant mailing lists. I would suggest, however, that the number of people that do read these lists run mail servers with more end users than the small system administrators that do not. The absence of a list such as I've described, the difficulty of creating of which you point out, makes it more unlikely to me that an organization can really assess the effects of unilateral design changes, especially when that assessment is shrouded in commercial secrecy. i don't disagree that it would be useful, but how are you going to build it without actively probing mail servers across the internet? and it can't possibly ever be complete, with PIX firewalls obscuring SMTP banners and sysadmins depending on security-by-obscurity who change their banners to elminate MTA identification. richard -- Richard Welty [email protected] Averill Park Networking 518-573-7592 Java, PHP, PostgreSQL, Unix, Linux, IP Network Engineering, Security
