i'm running a small network.. my gateway is 192.168.0.1 (or 24.x.x.x resolved to blah.com). i also have few clients as 192.168.0.2,3,4 question is: how do i send mail to those clients? they all are configured as blah.com since postfix wouldn't run if hostname is not FQDN. i can't mail to mark@192.168.0.2 - doesn't work.. any ideas?
