Desperate with fresh installation

I have problems with fresh install virtualmin. Vps Centos 6, 4096 Mb Openvz.

Only Real memory 1024 MB total, and Postfix Mail Server not start.

“The Postfix server does not appear to be installed on your system, or has not yet been set up properly in Webmin’s Postfix Configuration module. If you are running a different mail server, select it on the module configuration page.”

A week ago instaled virtualmin in this vps witth no problem.

can you help? Thks.

What happens when you start the postfix server?

Error while checking current Postfix configuration. Please manually fix Postfix configuration.

postfix: fatal: parameter inet_interfaces: no local interface found for ::1

What interfaces are configured in webmin > networking >network configuration > network interfaces?

That to me looks as though it is looking for a virtual interface - I may be wrong though


What output do you receive if you run the command “postconf -n”?


::1 is ipv6 localhost loopback

lo Loopback Yes venet0 OpenVZ 2a03:f80:ed15:ed15:ed15:ed15:2b9c:b12b 2a03:f80:ed15:ed15:ed15:ed15:c678:b27d 2a03:f80:ed15:ed15:ed15:ed15:fc27:6ed4 2a03:f80:ed15:ed15:ed15:ed15:945:2652 2a03:f80:ed15:ed15:ed15:ed15:9691:8ce5 2a03:f80:ed15:ed15:ed15:ed15:a0e8:43ac 2a03:f80:ed15:ed15:ed15:ed15:79c:bd71 2a03:f80:ed15:ed15:ed15:ed15:d1d5:e8d5 2a03:f80:ed15:ed15:ed15:ed15:d53f:9f04 2a03:f80:ed15:ed15:ed15:ed15:dade:d4cd Yes venet0:0 OpenVZ (Virtual) xx.xx.xx.xx

If you don’t require ipv6 support, you could set the inet_protocols line you have to this:

inet_protocols = ipv4

And then restart Postfix:

/etc/init.d/postfix restart

venet0:0 shows your public IP

Hi, work fine. Now all I need why I have only recognizes 1024 of real memory, when in vps have 4096.

Thanks all for your attention, greetings.


What does the command “free -m” show?


[root@vps ~]# free -m total used free shared buffers cached Mem: 4096 471 3624 0 0 137 -/+ buffers/cache: 334 3761 Swap: 0 0 0

Okay, and where are you seeing it say 1024MB of memory?


In the first page of panel virtualmin where is the features resume.
