3.5.2. Creating a User ID (UID) and Group ID (GID) for

postfix

Before you build and install postfix, be sure to create a  postfix  and a  postdrop 

user and group if they do not exist on the system. First check for the groups. You

can check this by

grep postfix /etc/group

and

grep maildrop /etc/group

If there are no such groups and users, you just create them. Search for a free

numeric UID and GID. In the following example I will use UID and GID 33333 for

Postfix and 33335 for the maildrop UID and GID. These ID's correspond to other

documents.

groupadd  g 33333 postfix

groupadd  g 33335 postdrop

useradd  u 33333  g 33333  d /dev/null  s /bin/false postfix

3.5.3. Building and installing

The following section shows what you have to do if you installed MySQL from

source as described above. If you installed MySQL from a binary package such as

rpm or deb, then you have to change the include and library flags to

 I/usr/include/mysql and  L/usr/lib/mysql.

Old MTA needs to be uninstalled

It is important that you uninstall any sendmail version from

RPM based systems. I suggest that you remove sendmail, and

install Postfix instead. At least SuSE RPMs need a MTA. After

installing the Postfix RPM, just install Postfix over the RPM

installation by following the HOWTO.

tar  xvzf postfix 2.0.19.tar.gz

cd postfix 2.0.19

make makefiles 'CCARGS= DHAS_MYSQL \
