Extmail邮件服务器部署

前言 extmail是一款开源的webmail系统。 现有的基于extmail的部署架构有如下两种模式：

第一种：postfix + extmail + devocot + courier-authdaemon 第二种：postfix + extmail + courier-authdaemon + courier-imap + courier-pop3 + maildrop 本次部署基于第二种模式进行配置 部署 部署环境 OS：ubuntu 11.04 server Extmail：1.2 Extman：1.1 依赖包安装 apt-get install mysql-client-5.1 mysql-server apache2 postfix postfix-mysql postfix-doc courier-authdaemon courier-authlib-mysql courier-pop courier-pop-ssl courier-imap courier-imap-ssl libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl libapache2-mod-fastcgi libfcgi-perl build-essential libtool libnet-server-perl libnet-cidr-perl libberkeleydb-perl arc zoo lzop liblzo2-dev libstdc++5 libgd-gd2-perl libfile-tail-perl libdigest-sha1-perl libdigest-HMAC-perl libnet-ip-perl libnet-dns-perl libhtml-tagset-perl libhtml-parser-perl libio-stringy-perl libio-multiplex-perl libio-socket-ssl-perl libio-zlib-perl libnet-ssleay-perl libunix-syslog-perl libtimedate-perl libmailtools-perl libconvert-binhex-perl libconvert-tnef-perl libconvert-uulib-perl libcompress-zlib-perl libarchive-zip-perl libarchive-tar-perl perl-suid 下载extmail和extman google一下即可找到官方下载地址，下载最新版本，可能看到文档的时候我这个版本已经不是最新，直接下最新的即可。 下载完毕之后将文档解压到/var/www/extsuite/extmail和/var/www/extsuite/extman 将postfix需要使用的虚拟主机的配置文件拷贝到postfix的etc文件夹下面 cp /var/www/extsuite/extman/docs/mysql_virtual_*.cf /etc/postfix/ 用户分配 特别说明：因为extmail系统里面使用的用户的uid和gid都是1000，如果你使用的ubuntu系统初始化一个admin用户，这个用户的 uid和gid就是1000，但是你又不想用此用户作为extmail的运行用户，那就必须新建一个用户，然后将此用户的uid和gid与初始化用户替 换。 useradd -m -d /home/www -s /bin/bash www passwd www 以上新建用户的uid和pid都是1001，可以修改passwd文件和group文件进行替换。 文件属性修改 chmod 755 /etc/postfix/mysql_virtual_*.cf chgrp postfix /etc/postfix/mysql_virtual_*.cf chown -R www:www /var/www/extsuite/extmail/cgi/ chown -R www:www /var/www/extsuite/extman/cgi/ cd /var/www/extsuite/extmail/ cp webmail.cf.default webmail.cf cd /var/www/extsuite/extman/ cp webman.cf.default webman.cf 修改extmail配置文件 vim /var/www/extsuite/extmail/webmail.cf SYS_USER_LANG = zh_CN # 语言设置 SYS_MYSQL_USER = extmail # 默认访问数据库的用户名 SYS_MYSQL_PASS = extmail # 默认访问数据库的密码 SYS_MYSQL_DB = extmail # 默认访问数据库的名字 SYS_MYSQL_SOCKET = /var/run/mysqld/mysqld.sock SYS_AUTHLIB_SOCKET = /var/run/courier/authdaemon/socket SYS_MAILDIR_BASE = /home/vmail SYS_MESSAGE_SIZE_LIMIT = 102400000 vim /var/www/extsuite/extman/webman.cf SYS_CAPTCHA_ON = 0 ##用于关闭后台登录时的验证码 SYS_MAILDIR_BASE = /home/vmail SYS_MYSQL_SOCKET = /var/run/mysqld/mysqld.sock SYS_LANG = zh_CN SYS_GROUPMAIL_SENDER = admin@1k8k.com vim /var/www/extsuite/extman/contrib/passwd2ext.pl my $sock = \'/var/run/mysqld/mysqld.sock\'; Extmail 数据库初始化 直接导入sql脚本 mysql -u root -pgaojinbo.com < /var/www/extsuite/extman/docs/extmail.sql mysql -u root -pgaojinbo.com < /var/www/extsuite/extman/docs/init.sql 临时文件夹建立 mkdir /tmp/extman chown -R www:www /tmp/extman 初始化postmaster@extmail.org帐户的Maildir文件夹 cd /var/www/extsuite/extman/tools ./maildirmake.pl /home/vmail/extmail.org/postmaster/Maildir chown -R www:www /home/vmail/extmail.org/ postfix配置 # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

apt-get install maildrop

vi /etc/maildropmysql.config //创建一个文件

修改/etc/maildroprc

vi /etc/maildroprc

logfile "/var/log/maildrop.log"

vi /var/log/maildrop.log

chown vuser:vgroup /var/log/maildrop.log chmod 766 /var/log/maildrop.log

vi /etc/logrotate.d/maildrop

/var/log/maildrop.log { daily notifempty missingok rotate 5 compress create 766 www www sharedscripts }

vi /etc/postfix/master.cf,注释掉原来maildrop的配置内容并改为:

maildrop unix - n n - - pipe flags=DRhu user=www argv=maildrop -w 90 -d ${user}@${nexthop} ${recipient} ${user} ${extension} {nexthop} #flags前面必须空2格

由于maildrop不支持一次接收多个收件人，因此必须在/etc/postfix/main.cf增加参数，已经在前面main.cnf里面添加，就是Maildrop config里面的配置

创建vi /etc/quotawarnmsg，为邮箱空间超过配额时的警告邮件内容：

X-Comment: Rename/Copy this file to quotawarnmsg, and make appropriate changes X-Comment: See deliverquota man page for more information From: Mail Delivery System Reply-To: support@example.com To: Valued Customer:; Subject: Mail quota warning Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 7bit Your mailbox on the server is now more than 90% full. So that you can continue to receive mail you need to remove some messages from your mailbox.

启动extman服务

/var/www/extsuite/extman/daemon/cmdserver -v -d

写入启机服务

echo "/var/www/extsuite/extman/daemon/cmdserver -v -d" >>/etc/rc.local
