exactly. and as some people in this list already pointed out: it is not. i don't like people to enforce their "strict" policies on me, unless these strict policies are legal. what's next? everybody needs to run an ident daemon on his mail server ? if you want to help your customers getting rid of their spam, why not force them to use a spam filter? oh, i forgot.. they pay you and we don't. it's pretty obvious, that as long as the reverse dns isn't in RFC, chances are that the good guys send mail from servers without reverse dns. => if you don't accept mail from them, your customers will lose "ham" mail. -- Mit internetten Grüßen / Best Regards --------------------------------------------------------------------------- Justin Heesemann ionium Technologies [EMAIL PROTECTED] www.ionium.org
