I have two centos 5.2 built. One on isp that does not block port 25 in/out. And one on isp that does. So i thought, i would use that smtp for the one that does not block 25 so i followed the relaying to isp's smtp server howto on this site. So now,when i look at the maillog it looks like this: mx00.mail.server.net[205.10.1.132]: No route to host (port 25). Now, the Port 25 does jump out in this message but more than that is the "no route to host". What does this mean? happz
The no route to host means that either you cannot connect to that machine or the port is being blocked.
