Connection refused to port 25 and 587 but sendmail listening on those ports.
Hi, I am new to this forum, and new to Linux, I have been working with it for ten months and I am a big fan now.
I have recently installed a set of virtualized servers with XenServer 5.5 that have one purpose only and that is sending emails. I have a central server whith Fedora 12 x86_64 that relays email to other servers ,that have minimal config, through a virtual interface created with Xen that works as a LAN. I have 3 CentOS 5.4 servers working fine in this setup and now I am trying out TurnKey Linux Core, just because its a Linux that has nothing on it, and that way I can use less memory. The problem is I cant seem to connect to port 25 or 587. The machine has shorewall installed and I am logging all traffic through the local interface and it shows the telnet request getting there. Doing a netstat shows sendmail listening on port 25 and 587. I really dont understand what can be wrong. Any help would be great. Thanks in advance.

Sendmail is listening on 127.0.0.1 interface, not 192.168.100.53. So try to reconfigure sendmail to listen on the correct interface.
