Still having the same problem

I still have the same error even after changing to localhost. I had created Maildir folders for the user so i dont know if this is what is creating the problem. Outlook can pick mail using imap accounts so i am wondering what is wrong with webmail?

I have just checked the mail log and this is what i got

Aug 26 15:41:50 mail imapd: Connection, ip=[::ffff:127.0.0.1]
Aug 26 15:41:54 mail authdaemond: failed to connect to mysql server (server=mysql.example.com, userid=admin): Unknown MySQL server host 'mysql.example.com' (1)
Aug 26 15:41:54 mail imapd: LOGIN FAILED, [email protected], ip=[::ffff:127.0.0.1]
Aug 26 15:41:54 mail imapd: authentication error: Input/output error

 

my /etc/hosts file

My hosts file looks like this

mail:~ # vi /etc/hosts
# Syntax:
#
# IP-Address Full-Qualified-Hostname Short-Hostname
#

127.0.0.1 localhost

# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.2 mail.uwasnet.org mail
192.168.1.2 mail mail
196.0.25.202 mail mail


so where and how do i add the directive?

Secondly i have a few sites for example: www.e-trademart.com (not registered) that i wanted to develop using the server. How can i have them working? I know ultimately i have to register them....just want to do a quick fix before that.

 

I have done

I have done the above but i still have the same error message. If i may ask when installing ispconfig it reconfigures postfix mail server. What are the configurations it puts in postfix? It seams i might have skipped or maybe told ispconfig not to configure postfix. Can you help me out?
