For some reason, when I try to telnet to localhost (at 14. in the how-to, page 5), I get no response #telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is bla-blah This looks normal, of course. But when I type "ehlo something", or anything at all, there is absolutely no replyn from the terminal. "quit" doesn't even quit, and the telnet session cannot be killed. I have to kill the terminal windows and open a new one to continue. Any ideas? Telnetting to pop3 (110) works fine, as do 10024 works. But 10025 fails in the same way. This tells me with no uncertainty that the problem is the SMTP server (Postfix), since both 25 and 10025 maps to that service. Correct me if I'm wrong.
What's the value of myorigin in /etc/postfix/main.cf? What's the output of Code: hostname and Code: hostname -f ? What's in /etc/hosts and /etc/resolv.conf?
Hmmm..for some reason, that line is just commented out: #$myorigin = $myhostname #$myorigin = $mydomain Both $myhostname and $mydomain was commented out also, but had the right values. I tried uncommenting $mydomain and $myhostname, then uncommenting $myorigin = $myhostname. Restarted postfix. No change. ldapmaster.testnet.com (the FQDN) The same as in just "hostname" 127.0.0.1 ldapmaster.testnet.com localhost.localdomain localhost dapmaster My name servers.
Make it look like this instead: Code: 127.0.0.1 localhost.localdomain localhost 1.2.3.4 ldapmaster.testnet.com ldapmaster Replace 1.2.3.4 with your system's IP address.
No help at all. Still the same - when telnetting to the SMTP server, it hangs so that I have to kill the terminal.
