Hi, I had to re-install my machine using stable distribution. This is my server running Exim, Cyrus, Apache etc. It seems that when I selected a bundle of packages at the installation, it had installed some kind of the firewall, or did some configuration I can't figure out. Namely, I can telnet to SMTP post locally (telnet 127.0.0.1 smtp) but I get "connection refused" when I try to telnet from a box on the same subnet. For that matter, I can telnet on that box to localhost but cannot telnet from any other machines on the same subnet. I removed ipchains already, but there must be something else. I am behind a hadware firewall, so I can get by without any software firewall. I already spent hours without any success chasing this problem.
Many thanks in advance -aaron
