Postfix Admin is a web based interface used to manage mailboxes, virtual domains and aliases. This article will show you how to install Postfix Admin to simplify management of mailboxes, domains and aliases.
Installing Postfix Admin
1. Install the Postfix Admin requirements using the command below.
yum install mysql-server php php-mysql php-imap php-mbstring
2. Download the latest stable version of Postfix Admin in .tar.gz format here. Assuming you got the file postfixadmin-2.2.1.1.tar.gzand it is located on your Desktop, type in the commands below to extract and to put it into its proper directory.
cd /usr/share tar -xvzf ~/Desktop/postfixadmin-2.3.5.tar.gz mv postfixadmin-2.3.5 postfixadmin
The PostfixAdmin archive has to be extracted directly into the /usr/share directory to enable Linux to apply the proper SELinux context into the files.
3. Edit the file /usr/share/postfixadmin/config.inc.php and update the following lines below.
$CONF['configured'] = true; $CONF['postfix_admin_url'] = '/postfixadmin'; $CONF['database_type'] = 'mysqli'; $CONF['database_host'] = 'localhost'; $CONF['database_user'] = 'postfix'; $CONF['database_password'] = 'your_password'; $CONF['database_name'] = 'postfix'; $CONF['domain_path'] = 'YES'; $CONF['domain_in_mailbox'] = 'NO'; $CONF['encrypt'] = 'cleartext'; $CONF['emailcheck_resolve_domain] = 'NO';

I am just a noob tryin to learn and get my feet wet while I am in school for Computer Science. I know how important it is to find the latest information to insure that I am following instructions for the correct version of RHEL. Imagine how pleased I was when I saw the date of your post, to find that I am, in fact, using information from the future. I guess I can’t get any more up to date. 🙂
The above referenced post was made in complete humor of course. Us silly americans are used to the date being stated in the mm/dd/yyyy format, and the post was made purely in jest.
Thank you for the great step by step. Worked great, my system is up and running perfectly.
I am just seeming both for blog sites which give independent, nutritious commentary on all difficulties or blogging sites which have a liberal or droppedwing slant. Thank you.. afdkafabddec
