利用Ubuntu ExtMail 30分钟配置好一个功能强大的邮件
尚 2010-05-21
利用Ubuntu ExtMail 30分钟配置好一个功能强大的邮件服务器V1.1,以下文档通过19个大的步骤进行配置，配置成功！
由于网上Ubuntu ExtMail的步骤特别多，看了都头痛，在此特别给朋友们制作了一个简洁的安装文档，希望大家喜欢:)
环境：
Ubuntu 8.04 TLS
postfix 2.5.1
ExtMail 1.2
extman 1.1
1.安装依赖包
apt-get install mysql-client-5.0 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 liblzo1 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
你会被询问以下问题：
Create directories for web-based administration? <– No
General type of mail configuration: <– Internet Site
System mail name: <– mail.extmail.org
2.下载extmail-1.2和extman-1.1,并修改配置
下载地址：http://www.extmail.org/download
tar xvzf extmail-1.2.tar.gz
tar xvzf extman-1.1.tar.gz
mkdir /var/www/extsuite
mv extmail-1.2/ /var/www/extsuite/extmail
mv extman-1.1/ /var/www/extsuite/extman
cp /var/www/extsuite/extman/docs/mysql_virtual_*.cf /etc/postfix/
注意,非常重要：修改/etc/postfix/mysql_virtual_*.cf,将其中的“localhost”均改为“127.0.0.1”,修改数据库配置，保证能够连到mysql
3.建立相关系统用户
1)新建普通用户
useradd -m -d /home/hugwww -s /bin/bash hugwww
passwd hugwww
2)删除以前gid,uid为1000的用户
userdel -r gaojinbo
3)建立extmail所需要的用户和组
groupadd -g 1000 vgroup
useradd -m -g vgroup -u 1000 -d /home/vmail -s /bin/false vuser
4.修改权限
chmod 755 /etc/postfix/mysql_virtual_*.cf
chgrp postfix /etc/postfix/mysql_virtual_*.cf
chown -R vuser:vgroup /var/www/extsuite/extmail/cgi/
chown -R vuser:vgroup /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
5.修改/var/www/extsuite/extmail/webmail.cf里的其他参数，主要变动的内容见下：
vi /var/www/extsuite/extmail/webmail.cf
SYS_USER_LANG = zh_CN
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_MYSQL_DB = extmail
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 //注：这个选项为修改附件的大小，默认为5M，你可以自行修改，这里面改了是不行的，还要去postfix里面修改,我在下面会讲到
6.修改 /var/www/extsuite/extman/webman.cf的参数
vi /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 = [email protected] //注：这个选项是，你在后台群发后，用户收到邮件的发件人地址，你可以自行修改
7.修改/var/www/extsuite/extman/contrib/passwd2ext.pl
my $sock = ‘/var/run/mysqld/mysqld.sock’;
9.建立临时文件夹：
mkdir /tmp/extman
chown -R vuser:vgroup /tmp/extman
if [ ! -d /tmp/extman ]; then
mkdir /tmp/extman
chown -R vuser:vgroup /tmp/extman
fi
10.建立上边导入mysql的[email protected]帐户的Maildir，请输入如下命令：
cd /var/www/extsuite/extman/tools
./maildirmake.pl /home/vmail/extmail.org/postmaster/Maildir
chown -R vuser:vgroup /home/vmail/extmail.org/
11.Postfix配置
cd /etc/postfix/
cp main.cf main.cf_backup
vi main.cf
# TLS parameters
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
smtpd_use_tls = yes
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
mydomain = extmail.org
myhostname = mail.$mydomain
myorigin = $mydomain
mydestination = mail.$mydomain, localhost.$mydomain, localhost
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
relayhost =
mynetworks = 127.0.0.1
message_size_limit = 102400000
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
html_directory = /usr/share/doc/postfix/html
######### virtual config############
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_limit_maps.cf
virtual_mailbox_base = /home/vmail
virtual_uid_maps = static:1000
virtual_gid_maps = static:1000
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_overquota_bounce = yes
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry, the your Maildir has overdrawn your diskspace quota, please free up some of spaces of your mailbox try again.
proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps
重启 postfix
/etc/init.d/postfix restart
12.SMTP身份认证
cd /etc/postfix
openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout smtpd.key -keyform PEM -days 365 -x509
14.编辑/var/www/extsuite/extmail/dispatch-init文件：
vi /var/www/extsuite/extmail/dispatch-init
MAXFORK=10
最后启动fastcgi server：
/var/www/extsuite/extmail/dispatch-init start
如果没有意外将启动10个dispatch.fcgi守护进程，可以通过以下命令将启动命令加到rc.local中，实现自启动：
echo "/var/www/extsuite/extmail/dispatch-init start">>/etc/rc.local
15.SMTP认证
1).更改saslauthd
vi /etc/default/saslauthd
更改如下几项
START=yes //设置开机自动启动
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"
2). 创建文件/etc/pam.d/smtp
vi /etc/pam.d/smtp
内容如下：
auth required pam_mysql.so user=extmail passwd=extmail host=127.0.0.1 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1
account sufficient pam_mysql.so user=extmail passwd=extmail host=127.0.0.1 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1
解释一下：其实就是定义一个查询的方式 crypt=1或者0表示加密或者不加密 注意对照你的数据库还有用户名密码 请保持跟自己的一致
3).由于postfix处于chroot，要想调用到saslauthd 必须更改socket文件
mkdir -p /var/spool/postfix/var/run/saslauthd
vi /etc/postfix/sasl/smtpd.conf
创建smtpd.conf，并且内容如下：
pwcheck_method:saslauthd
mech_list:plain login
allow_plaintext: true
auxprop_plugin: mysql
sql_hostnames: 127.0.0.1
sql_user: extmail
sql_password: extmail
sql_database: extmail
log_level:7
sql_select: SELECT password FROM mailbox WHERE username=’%u@%r’ and domain=’%r’
4).更改main.cf 文件
vi /etc/postfix/main.cf
###########SMTP AUTH config###############
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
###########smtpd related config############
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_sender_login_mismatch, reject_unknown_sender_domain, reject_non_fqdn_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, reject_unauth_pipelining, reject_invalid_hostname, check_recipient_maps
5).添加用户
adduser postfix sasl
6).重启postfix saslauthd
/etc/init.d/postfix restart
/etc/init.d/saslauthd restart
7).测验
telnet localhost 25
Trying 127.0.0.1…
Connected to localhost.
Escape character is ‘^]’.
220 mail.extmail.org ESMTP Postfix
ehlo localhost

235 2.7.0 Authentication successful
quit
221 2.0.0 Bye
Connection closed by foreign host.
如果出现Authentication successful 表示没有问题了
16.POP验证
vi /etc/courier/authdaemonrc
#更改如下一项
authmodulelist="authmysql"
cp /etc/courier/authmysqlrc /etc/courier/authmysqlrc_orig
cat /dev/null > /etc/courier/authmysqlrc
vi /etc/courier/authmysqlrc
#内容如下：
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail
MYSQL_SOCKET /var/run/mysqld/mysqld.sock
MYSQL_PORT 3306
MYSQL_OPT 0
MYSQL_DATABASE extmail
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password
MYSQL_UID_FIELD uidnumber
MYSQL_GID_FIELD gidnumber
MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD homedir
MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD maildir
MYSQL_QUOTA_FIELD quota
MYSQL_SELECT_CLAUSE SELECT username,password,"",uidnumber,gidnumber,\
CONCAT(‘/home/vmail/’,homedir), \
CONCAT(‘/home/vmail/’,maildir), \
quota, \
name, \
CONCAT("disablesmtpd=",disablesmtpd, \
",disablesmtp=",disablesmtp, \
",disablewebmail=",disablewebmail, \
",disablenetdisk=",disablenetdisk, \
",disableimap=",disableimap, \
",disablepop3=",disablepop3, \
",netdiskquota=",netdiskquota) \
FROM mailbox \
WHERE username = ‘$(local_part)@$(domain)’
配置Courier-POP3
vi /etc/courier/pop3d
MAILDIRPATH=/home/vmail/
配置Courier-IMAP
vi /etc/courier/imapd
MAILDIRPATH=/home/vmail/
重新启动
/etc/init.d/courier-authdaemon restart
/etc/init.d/courier-imap restart
/etc/init.d/courier-imap-ssl restart
/etc/init.d/courier-pop restart
/etc/init.d/courier-pop-ssl restart
测试Courier- Authlib是否能成功连接mysql
authtest -s login [email protected] extmail
如果成功应该有如下显示
Authentication succeeded.
Authenticated: [email protected] (uid 1000, gid 1000)
Home Directory: /home/vmail/extmail.org/postmaster
Maildir: /home/vmail/extmail.org/postmaster/Maildir/
Quota: 104857600S

+OK Password required.
pass extmail
+OK logged in.
list
+OK POP3 clients that break here, they violate STD53.
.
quit
+OK Bye-bye.
Connection closed by foreign host.
如果出现问题请仔细分析日志
17.图形日志extmail
apt-get install mailgraph
cp -r /var/www/extsuite/extman/addon/mailgraph_ext/ /usr/local/mailgraph_ext
vi /usr/local/mailgraph_ext/mailgraph-init为：
MAIL_LOG=/var/log/mail.log
然后复制文件
cp /var/www/extsuite/extman/addon/mailgraph_ext/mailgraph-init /etc/init.d/mailgraph
cp /var/www/extsuite/extman/addon/mailgraph_ext/qmonitor.pl /etc/init.d/qmonitor
启动服务
/etc/init.d/mailgraph start
18.安装Maildrop
apt-get install maildrop
vi /etc/maildropmysql.config //创建一个文件
hostname localhost
port 3306
database extmail
dbuser extmail
dbpw extmail #修改为您的密码
dbtable mailbox
default_uidnumber 1000
default_gidnumber 1000
uidnumber_field uidnumber
gidnumber_field gidnumber
uid_field username
homedirectory_field concat(‘/home/vmail/’,homedir,’/’)
maildir_field concat(‘/home/vmail/’,maildir)
quota_field quota
mailstatus_field active
修改/etc/maildroprc
vi /etc/maildroprc
logfile "/var/log/maildrop.log"
手动创建日志
vi /var/log/maildrop.log
chown vuser:vgroup /var/log/maildrop.log
chmod 766 /var/log/maildrop.log
vi /etc/logrotate.d/maildrop
内容为下面：
/var/log/maildrop.log {
daily
notifempty
missingok
rotate 5
compress
create 766 vuser vgroup
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=vmail argv=maildrop -w 90 -d ${user}@${nexthop} ${recipient} ${user} ${extension} {nexthop}
由于maildrop不支持一次接收多个收件人，因此必须在/etc/postfix/main.cf增加如下参数:
vi /etc/postfix/main.cf
###### Maildrop config ########
maildrop_destination_recipient_limit = 1
virtual_transport = maildrop:
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 <[email protected]>
Reply-To: [email protected]
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.
19.解决extman问题
1）修改相关服务路径
vi /var/www/extsuite/extman/daemon/cmd_plugin/linux-cmd
2）启动服务
/var/www/extsuite/extman/daemon/cmdserver -v -d
3)写入rc.local开机自动运行
echo "/var/www/extsuite/extman/daemon/cmdserver -v -d" >>/etc/rc.local
