hi, i´m a bit in trouble for now. i set up qmail and all works ok. then i use /etc/aliases with fastforward, and after that the machine acts as a relay. following situation : we are hosting serveral domains, each has for example a [EMAIL PROTECTED] etc. there is also an old mail-server using a different domain which is actually the "real" mail server where our staff get its mail from. so the new server has to do following : all mail for domain foo.com should go to bar.com mail from [EMAIL PROTECTED] should go to [EMAIL PROTECTED] mail from [EMAIL PROTECTED] should also go to me mail from [EMAIL PROTECTED] should go to [EMAIL PROTECTED] mail from [EMAIL PROTECTED] should go to [EMAIL PROTECTED] and so on.... only known rcpts should be allowed, so i put all our domains in in rcpthosts and locals smptroutes shows: real.mail:[12.34.56.78] but i can send mail to ANY host. ANYbody can do that. how to stop that ? please, please help........ it drives me nuts......
