Advice

Until 2.2 version Postfix supports IPv4, but it is disabled by default

 

How to check Postfix version

Instalation from source

Instalation from repository 

Configuration inet_protocols

Configuration inet_interfaces

 

To check Postfix version we have to open terminal and use command "postconf mail_version"

 

To install Postfix from source, we have to dovnload source code from official site of Postfix  http://www.postfix.org/download.html .

We also have to install packages which are required:

perl

gcc

db*-devel

To install them we have to be logged as superuser. Then we use command  "zypper install perl gcc db*-dovel libdb4.7-dev" and confirm  all request from system during  installation.

After install packages and download source code from official site we have to be in directory where is source code with Postfix.

Execute command  "tar xzf file_name.tar.gz" we unpack the source. Then we go to directory creating during unpach action and write command "make". After execute command we have to create new group and user by  "groupadd group_name" oraz "useradd user_name" commands. To any ask from system during installation we have to press "Enter" expect ask about   mail_owner and setgid_group. There write name user and group which you created before.

 

Instalation from repository

To install Postfix from repository execute  "zypper install postfix"  command logged as superuser 


 

We have to find line which begins  "inet_protocols".  Default value is "ipv4" (as the folowing ilustration).
