I'm following the howto guide outlined here:
While following this guide, when I was supposed to connect to port 25 using telnet, I did not get the expected results. I got no results. No error message, no nothing, I could type anything I wanted, and I got no feedback. I had to quit by pressing ctrl-] and then type "quit" to get out of the telnet console. Since this was just for postfix, and it didn't seem to prevent postfix from starting, I ignored it and moved on.
Now I've followed the guide to the end, ISPconfig2 is installed and running, and all seems well... except postfix won't start. I get the following error message:
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Starting mail service (Postfix) failed
