Second, installation Postfix

Postfix is an MTA (mail transfer agent) software developed by Wietse Venema under the GPL of IBM to replace SendMail, which is faster, more robust, more flexible, more secure, and more compatible than SendMail.

Official website: http://www.postfix.org/

1. Installation

[[email protected] ~]# Rpm-aq|grep postfixpostfix-2.6.6-2.2.el6_1.x86_64#centos6.5 has been installed by default version 2.6.6, then upgrade: [Email Protected] ~]# Yum update postfixpostfix-2.6.6-6.el6_5.x86_64

CentOS 7 has a built-in version of 2.10.1, and for the time being no research has been done to improve it, and will release 7 builds in the future.

[[email protected] postfix]# postfix check# No error return indicates the configuration is correct [[email protected] postfix]# postconf-a# appears Cyrus indicates that the Cyrus authentication user can be supported [[email protected] postfix]# postconf-m# appears MySQL indicates that MySQL storage account can be supported

5. Set up a firewall

[[email protected] ~]# iptables-i input-p TCP--dport 25-j accept[[email protected] ~]# service Iptables Save

Third, installation Courier-authlib

Courier-authlib is a data authentication library responsible for Courier-imap,maildrop certification.

Official website: http://www.courier-mta.org

1. Installation

Http://www.courier-mta.org/download.html#authlib

The following packages are required for the download page:

courier-authlib-0.66.1.tar.bz2courier-unicode-1.1.tar.bz2courier-imap-4.15.1.tar.bz2maildrop-2.7.2.tar.bz2

I have uploaded to the Download Center for free Download:

Install Courier-authlib:

#先查看下uid  1000 has used [[email protected] ~]# cat /etc/passwd#] to create a user when installing the system, taking up 1000 So use 1002[[email protected] ~]# groupadd vmail -g 1002 [[email  protected] ~]# useradd vmail -u 1002 -g 1002 -d /home/domains[[ email protected] ~]# cd /usr/local/src[[email protected] src]# wget  http://cznic.dl.sourceforge.net/project/courier/authlib/0.66.1/courier-authlib-0.66.1.tar.bz2[[email  Protected] src]# tar -jxf courier-authlib-0.66.1.tar.bz2 [[email protected]  src]# cd courier-authlib-0.66.1 [[email protected] courier-authlib-0.66.1]#  ./configure --with-mysql-libs --with-mysql-includes --with-authmysql -- with-authmysql=yes --with-mailuser=vmail --with-mailgroup=vmail[[email protected]  Courier-authlib-0.66.1]# make [[email protected] courier-authlib-0.66.1]# make install [[email protected] courier-authlib-0.66.1 ]# make install-configure

Description: Error may occur at compile time, basically because some packages are not installed, Yum is loaded and recompiled, so it is recommended to first install the dependent software according to the "system environment" above.
The MySQL parameter can also specify an absolute path:
--with-mysql-libs=/usr/local/mysql/lib/mysql\
--with-mysql-includes=/usr/local/mysql/include/mysql/\

Iv. installation of Maildrop

Maildrop is a local mail delivery agent (MDA) that supports filtering (/ETC/MAILDROPRC), posting, and disk quota (Quota) capabilities.

Maildrop with RPM package installation will automatically create VUser users and Vgroup user groups, specifically for the storage of mail; Using source installation requires manually creating users and user groups with IDs greater than 1000, which is the user Vmail (1002) and group Vmail created above (1002) , and home directory/home/domain is the mail storage directory, the next section installs webmail will speak.

1, installation Courier-unicode

The character set library file, equivalent to the RPM installation of the Courier-authlib-devel package, does not install this will result in compiling the maildrop times wrong:

Configure:error:The Courier Unicode Library appears is installed. Need to install a separate development subpackage, in addition to the main package

[Email protected] ~]# cd/usr/local/src[[email protected] src]# wget http://jaist.dl.sourceforge.net/project/courier/ Courier-unicode/1.1/courier-unicode-1.1.tar.bz2[[email protected] src]# tar-jxf Courier-unicode-1.1.tar.bz2[[email Protected] src]# CD Courier-unicode-1.1[[email protected] courier-unicode-1.1]#./configure[[email protected] courier-unicode-1.1]# make && make install

2, Installation Maildrop

[Email protected] ~]# cd/usr/local/src[[email protected] src]# wget http://jaist.dl.sourceforge.net/project/courier/ Maildrop/2.7.2/maildrop-2.7.2.tar.bz2[[email protected] src]# tar-jxf maildrop-2.7.2.tar.bz2[[email protected] src]# CD Maildrop-2.7.2[[email protected] maildrop-2.7.2]#./configure--enable-maildirquota--enable-maildrop-uid=1002-- enable-maildrop-gid=1002--with-trashquota[[email protected] maildrop-2.7.2]# Make[[email protected] maildrop-2.7.2] # make Install

3. Configuration

[Email protected] maildrop-2.7.2]# vi/etc/postfix/master.cfmaildrop unix-n N-- Pipe Flags=drhu user=vmail argv=maildrop-w 90-d ${user}@${nexthop} ${recipient} ${user} ${extension} {nexthop}

[[email protected] maildrop-2.7.2]# vi/etc/postfix/main.cf# control maildrop processing only one message at a time Maildrop_destination_recipient_ Limit = 1

Description: User Vmail and group Vmail will be accustomed to the entire mail system, be sure to remember their name Vmail and ID number 1002, if not the same as set up in this article, please modify it to your own when compiling and configuring.

Conclusion: The basic structure of the mail system is set up, the MTA and MDA are in the background, and the next section will build the foreground webmail.
