My postfix mail won't deliver to any destination that is not local. Local user to user is fine. I'm getting a "(connect to smtp2.infotechsys.com: Connection timed out)" on all outbound mail. I check the FAQ and it said to disable MTU but the only thing close that I can see in the kernel was "net.ipv4.ip_no_pmtu_disc" it was originally set for 0 and I set it to 1 with no luck. What am I doing wrong? Configuration is the standard setup that comes in the RPM. Also how do I allow relaying from specific addresses in postfix? Thanks 6.1
