Hi there, I'm new to this. I'm trying to learn to setup a Linux E-mail server. Printed out the "The Perfect Setup - Fedora Core 5 (64 Bit)" I faced the foolowing message when I tried to telnet to see if SMTP-AUTH and TLS work properly. Quote [root@svr1 ~]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. Connection closed by foreign host.

Are there any errors in /var/log/maillog? What's the output of Code: netstat -tap ? What happens when you run Code: /etc/init.d/postfix restart ?

What's in /etc/hosts and /etc/resolv.conf? What's the output of Code: hostname and Code: hostname -f ?
/etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 195.100.100.50 svr1.abc.com svr1 ::1 svr1.abc.com svr1 localhost.localdomain localhost /etc/resolv.conf search abc.com nameserver 210.193.xxx.xxx nameserver 165.21.xxx.xxx nameserver 202.172.xxx.xxx [root@svr1 ~]# hostname svr1.abc.com [root@svr1 ~]# hostname -f svr1.abc.com [root@svr1 ~]#
In regards the IP address and domain, when I reply to you, I would normally change to 192.168.xxx.xxx and svr1.abc.com I would double check that the output in the actual tally as the output as what it is suppose to show. What other checks do I need to do please.
I'm sorry, the correct command is Code: postfix check Please also change Code: 195.100.100.50 svr1.abc.com svr1 to Code: 192.168.1.xxx svr1.abc.com svr1 in /etc/hosts (replace xxx with the real number) and run Code: postconf -e 'myhostname = svr1.abc.com' /etc/init.d/postfix restart
Hi Falko thanks for your help. However the reply came a bit late. I decided to reformat and start the whole process from the begining. This time round the postfix installed perfectly. However I'm still facing the problem with mysqladmin. It's the same with some new users I noticed. Somehow when we execute the command shell> myseladmin -h localhost -u root password 'ourmysqlpassword' we would be prompted with something like mysqladmin : connect to server at 'localhost' failed error: 'Access denied for user: 'root'@'localhost' (Using password: NO)' I'm not an expert, somehow something tell me that there is a configuration somewhere which states that there is no password in place and that's why it reject the command. I would read on this matter in the forum submitted by other people first before I start a new one. Another thing. Noted the following yum commands no longer works a) yum install webalizer b) yum install phpmyadmin once again thank you
Please try Code: mysqladmin -u root password yourrootsqlpassword What's the output? Also, what's the output of Code: netstat -tap ? Did you disable SELinux?
