Hi all ! I want to say first that I am fairly new in sysadmin and all server stuff, so please, be indulgent. I am not new at using linux though, but I never worked with a Debian distro. So, I have read the tutorial iRedMail: Mail Server With LDAP, Postfix, RoundCube/SquirrelMail, Dovecot, ClamAV, SpamAssassin, Amavisd (Debian 5.0.1) to install a mail server and I got some errors that I don't really understand and for wich I am unable to fix. I am not sure I fully understand the concept of hosts and hostname and in fact I don't know if I set them up correctly. One other thing : since I do all the admin stuff on my server trough ssh in root user, I don't know if I had done the right thing when I run the iRedMail script. I don't know all about the sudo su- thing in Debian, so since I was already root user, I didn't do the sudo su- thing when I ran the iRedMail script. Here's some of the output I got after the end of the iRedMail wizard : So I cannot login to /roundcube or /postfix via the webbrowser. Thanks in advance for you're help.
