RMX or on the other way AMTP is not the 'super-duper-solution' aginst spam ;-) there will be people dont know how to configure or even implement it. and even if implemented where will be some problems. let's say you host domain XYZ.com and allow your customers to send email from your ip range. what if that company has people in germany working for it, then you have to allow whole t-online? what if the spammer uses not a real domain but a dynamical domain (e.g. dyndns or XYZ.ch.vu). he might be allowed to send mail out. i'm sure spammers can circument those configurations with own infrastructure of something like that. and dont forget: you will never put a rule "dont accept mail from NON-RMX / AMTP servers". because you know, that the internet is fast growing but slow changing. remember IPv6? how many providers world-wide have implemented it yet? 2% 1%? i dont know. but i dont know many people reading NOW this list will be able to see IPv4 disappearing from the net... -steven ---------------------------------------------- [EMAIL PROTECTED] Maillist-Archive: http://www.mail-archive.com/swinog%40swinog.ch/
