ASMTP is a nearly useless solution, since most users using outlook and other Mailclients which are storing passwords.. any worm should be able to use the cached passwords.. or using mapi to send worms thru outlook which of course will authenticate with the cached password in the background. . CC smtp relay is even only usable as an relay from customers of CC so why made shure this is a CC user when the user can only relay from CC ranges ? There are users arround in the CC network which are not costumers of CC ? .. this would be then a more seriously problem
We are blocking dynamic ranges and the amazing reduced amount of spam and worms beside of some very rarely false block's telling us this is a good way. but i know, it harms all the expensive Spamsolutions and spamfiltering Providers btw: i never understand why using a far away smtp relay when most isp's offer an SMTP server to the customer of them ? travelling users are an exception, but there are a lot of solutions anyway .. most traveling users using ssl or vpn solutions to connect to the company network, even using almost the company mailsytem like exchange notes .... only my thought.. of course > No, it hopefully won't - and _if/when_ SPF (or anything like that) > will be implemented world wide you can't filter smtp traffic.
