This is my first attempt at creating a mail server. I'm running postfix and dovecot on Fedora 7. So far the process has been very enlightening. I currently have the server able to send and receive messages for a domain from the server machine itself. In addition, I can SMTP from any client set up on the LAN by logging in. However, I cannot retrieve messages from remote clients on the LAN. Thunderbird reads "Connected to" {servername} across the bottom, then times out. I tried to telnet to port 110 on the server, and I no response, just hangs. Not sure where the problem lies. Thanks for any assistance.
Stop Dovecot and try telnetting to port 110 again. Does it still hang? If so, change your firewall settings.
