Download the qmail supply tarball at http://cr.yp.to/software/qmail-1.03.tar.gz
Extract the ASCII text file.
Preparation for collecting involves adding 2 teams and seven user accounts employed by qmail.
mkdir /var/qmail
groupadd nofiles
useradd -s /sbin/nologin -g nofiles -d /var/qmail/alias alias
useradd -s /sbin/nologin -g nofiles -d /var/qmail qmaild
useradd -s /sbin/nologin -g nofiles -d /var/qmail qmaill
useradd -s /sbin/nologin -g nofiles -d /var/qmail qmailp
groupadd qmail
useradd -s /sbin/nologin -g qmail -d /var/qmail qmailq
useradd -s /sbin/nologin -g qmail -d /var/qmail qmailr
useradd -s /sbin/nologin -g qmail -d /var/qmail qmails
Change directory into the qmail ASCII text file directory. (cd qmail-1.0.3)

groupadd -g ninety one vchkpw
useradd -g vchkpw -u ninety one vpopmail
Extract the ASCII text file from the tarball and alter directory into the ASCII text file directory.
./configure --enable-mysql-replication --enable-sql-logging --enable-auth-module=mysql --disable-users-big-dir --enable-valias
This will provide North American country the choice to use a master MySQL server wherever writes for work, user/domain creation square measure sent and mysql slaves that square measure used just for reading user/domain info by vpopmail and alternative software package through its library. --enable-valias tells vpopmail to store email aliases during a MySQL information instead of .qmail files that we'll not be exploitation. All email addresses are hold on in one single table during this setup and aliases during a separate table.
make

It will so give the glue between vpopmail and these software package like drop. you'll be able to transfer courier-authlib and drop from http://sourceforge.net/project/showfiles.php?group_id=5404
courier-authlib
courier software package won't compile underneath the basis account. Also, to urge courier-authlib to select vpopmail libraries, you would like to be ready to access them throughout the configuration of the build method. it's instructed so that you just use the vpopmail user for the build method of courier-authlib. The courier-authlib supply desires atiny low patch to create it absolutely use vpopmail: courier-authlib-vpopmail.patch.
patch -p1 < courier-authlib-vpopmail.patch
cd courier-authlib-0.58
./configure --prefix=/usr/lib/courier --with-redhat \ --with-mailuser=vpopmail --with-mailgroup=vchkpw \ --with-mysql-libs=/usr/lib/mysql \ --with-mysql-includes=/usr/include/mysql
