注:默认密码为空

3.2安装postfix

#apt-get install postfix postfix-doc postfix-tls postfix-mysql

3.3 安装SASL2

#apt-get install libsasl2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl libpam-modules libpam-mysql

3.4 安装COURIER

#apt-get install courier-base courier-pop courier-imap courier-authdaemon courier-authlib-mysql

 

4.配置

4.1配置postfix

#cd /etc/postfix

 

#mv main.cf main.cf.bak

 

#vi main.cf

 

加入内容:

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

smtpd_use_tls=yes

smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache

smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for

myhostname = vip.eol.cn

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = /etc/mailname

mydestination =

relayhost =

mynetworks = 0.0.0.0/8

inet_interfaces = all

 

#=====================MySQL=====================

virtual_alias_maps = mysql:/etc/postfix/mysql/mysql_virtual_alias_maps.cf

virtual_uid_maps = static:105

virtual_gid_maps = static:105

virtual_mailbox_base = /home/domains

virtual_mailbox_domains = mysql:/etc/postfix/mysql/mysql_virtual_domains_maps.cf

virtual_mailbox_limit = 51200000

virtual_mailbox_maps = mysql:/etc/postfix/mysql/mysql_virtual_mailbox_maps.cf

virtual_minimum_uid = 105

virtual_transport = virtual

#=====================Quota=====================

virtual_create_maildirsize = yes

virtual_mailbox_extended = yes

virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql/mysql_virtual_mailbox_limit_maps.cf

virtual_mailbox_limit_override = yes

virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.

virtual_overquota_bounce = yes

#=====================SASL2====================

smtpd_sasl_auth_enable = yes

smtpd_sasl_security_options = noanonymous

broken_sasl_auth_clients = yes

smtpd_delay_reject=yes

smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,permit_auth_destination,reject

smtpd_client_restrictions = permit_sasl_authenticated

创建mysql虚拟配置文件:

#mkdir mysql

 

#cd mysql

 

#vi /etc/postfix/mysql/mysql_virtual_alias_maps.cf

 

加入:

user = extmail

password = extmail

#hosts = localhost

hosts = 219.224.99.244

dbname = extmail

table = alias

select_field = goto

where_field = address

additional_conditions = AND active = '1'

 

#vi /etc/postfix/mysql/mysql_virtual_domains_maps.cf

 

加入:

user = extmail

password = extmail

#hosts = localhost

hosts = 219.224.99.244

dbname = extmail

table = domain

select_field = domain

where_field = domain

additional_conditions = AND active = '1'

#vi /etc/postfix/mysql/mysql_virtual_mailbox_maps.cf

加入:

user = extmail

password = extmail

#hosts = localhost

hosts = 219.224.99.244

dbname = extmail

table = mailbox

select_field = maildir

where_field = username

additional_conditions = AND active = '1'

 

#vi /etc/postfix/mysql/mysql_virtual_mailbox_limit_maps.cf

加入:

user = extmail

password = extmail

#hosts = localhost

hosts = 219.224.99.244

dbname = extmail

table = mailbox

select_field = quota

where_field = username

additional_conditions = AND active = '1'

 

4.2配置smtp

#vi /etc/default/saslauthd

start=no改成yes

#vi /etc/postfix/sasl/smtpd.conf

加入:

pwcheck_method: authdaemond

log_level: 7

mech_list: plain login

authdaemond_path:/var/run/courier/authdaemon/socket

 

# vi /etc/pam.d/smtp

加入:

auth    required  pam_mysql.so user=extmail passwd=extmail host=202.205.109.7 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1

account sufficient pam_mysql.so user=extmail passwd=extmail host=202.205.109.7 db=extmail table=mailbox usercolumn=username passwdcolumn=password crypt=1

4.3配置pop3

# vi /etc/courier/pop3d

修改下面一些地方:

POP3AUTH="" 改为POP3AUTH=" CRAM-MD5"

 

#mv /etc/courier/authdaemonrc /etc/courier/authdaemonrc.bak

#vi /etc/courier/authmodulelist

修改认证模式为authmysql

# mv /etc/courier/authmysqlrc /etc/courier/authmysqlrc.bak

#vi /etc/courier/authmysqlrc

加入:

MYSQL_SERVER    219.224.99.244

MYSQL_PORT 3306

MYSQL_USERNAME   extmail

MYSQL_PASSWORD   extmail

MYSQL_SOCKET   /var/run/mysqld/mysqld.sock
