postfix安装

原创 Linux操作系统 作者:tengrid 时间:2009-05-18 19:56:29 0 删除 编辑
1.安装mysql并创建用户库结构
导入postfixadmin中自带的用户库结构
tar zxf postfix/postfixadmin-2.1.0.gz
cd postfixadmin-2.1.0/
/usr/local/mysql/bin/mysql -u root < DATABASE_MYSQL.TXT

2.安装Cyrus-sasl2
tar zxf postfix/cyrus-sasl-2.1.22.tar.gz
cd cyrus-sasl-2.1.22/
./configure --enable-plain --enable-cram --enable-digest --enable-login --enable-sql --disable-anon --disable-ntlm --disable-gssapi --disable-krb4 --disable-otp --disable-srp --disable-srp-setpass --with-authdaemond=/usr/local/var/spool/authdaemon/socket --with-mysql=/usr/local/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mysql-libs=/usr/local/mysql/lib/mysql
make
make install
ln -s  /usr/local/lib/sasl2 /usr/lib/sasl2
创建/usr/local/lib/sasl2/smtpd.conf文件,内容如下
pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/usr/local/var/spool/authdaemon/socket

3.安装Postfix
groupadd -g 10000 postfix
useradd -u 10000 -d /nonexistent -s /bin/false -g postfix postfix
groupadd -g 10001 postdrop
因postfix-2.4版需要epoll支持,所以只能安装postfix-2.3.12
tar zxf postfix/postfix-2.3.12.tar.gz
cd postfix-2.3.12/
make tidy
make makefiles CCARGS='-DHAS_MYSQL -DUSE_SASL_AUTH -DUSE_CYRUS_SASL \
-I/usr/local/mysql/include/mysql -I/usr/local/include/sasl'  AUXLIBS='-L/usr/local/mysql/lib/mysql -L/usr/local/lib \
-lmysqlclient -lm -lz -lsasl2'
make
ldconfig
make install
编辑/etc/postfix/main.cf文件,修改和添加如下内容(部分内容在make install时的交互脚本中完成设置)

queue_directory = /data/postfix_queues
myhostname = mail2.xxx.com
mydomain = xxx.com
myorigin = $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost
alias_maps = hash:/etc/postfix/aliases
home_mailbox = Maildir/

# virtual mailbox setup

virtual_mailbox_domains = mysql:/etc/postfix/mysql/mysql_mailbox_domains.cf
virtual_mailbox_base = /data/postfix_mailbox/
virtual_mailbox_maps = mysql:/etc/postfix/mysql/mysql_mailbox_maps.cf
virtual_minimum_uid = 10000
virtual_uid_maps = static:10000
virtual_gid_maps = static:10000
virtual_alias_maps = mysql:/etc/postfix/mysql/mysql_alias_maps.cf

# SASL setup
smtpd_sasl_auth_enable = yes
smtpd_sasl_application_name = smtpd
broken_sasl_auth_clients = yes
smtpd_sasl_local_domain = $mydomain
smtpd_recipient_restrictions = permit_mynetworks,
        permit_sasl_authenticated,reject_unauth_destination

# amavisd-new setup
content_filter = smtp-amavis:[127.0.0.1]:10024

同时根据/etc/postfix/main.cf文件中的虚拟邮箱设置,创建如下目录、文件和对应内容,具体的用户名和密码取决于mysql中的设置

mkdir /etc/postfix/mysql

cat /etc/postfix/mysql/mysql_alias_maps.cf
user = postfix
password = postfix
dbname = postfix
hosts = localhost
table = alias
select_field = goto
where_field = address
additional_conditions = and active='1'

cat  /etc/postfix/mysql/mysql_mailbox_maps.cf
user = postfix
password = postfix
dbname = postfix
hosts = localhost
table = mailbox
select_field = maildir
where_field = username
additional_conditions = and active='1'

cat /etc/postfix/mysql/mysql_mailbox_domains.cf
user = postfix
password = postfix
dbname = postfix
hosts = localhost
table = domain
select_field = domain
where_field = domain
additional_conditions = and active='1'

4.安装courier-authlib
tar jxf postfix/courier-authlib-0.59.3.tar.bz2
cd courier-authlib-0.59.3/
./configure --without-authpam --without-authldap --without-authpwd --without-authshadow --without-authvchkpw --without-authpgsql  --without-authcustom --without-authpipe --without-authuserdb --with-authmysql --with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql --with-mailuser=postfix --with-mailgroup=postfix
make
make install
echo "/usr/local/lib/courier-authlib" >> /etc/ld.so.conf
ldconfig
make install-configure

修改/usr/local/etc/authlib/authmysqlrc文件为如下内容
MYSQL_SERVER            localhost
MYSQL_USERNAME          postfix
MYSQL_PASSWORD          postfix

MYSQL_SOCKET            /tmp/mysql.sock

MYSQL_PORT              3306

MYSQL_OPT               0

MYSQL_DATABASE          postfix

MYSQL_USER_TABLE        mailbox

MYSQL_CRYPT_PWFIELD     password

DEFAULT_DOMAIN          xxx.com

MYSQL_UID_FIELD         10000

MYSQL_GID_FIELD         10000

MYSQL_LOGIN_FIELD       username

MYSQL_HOME_FIELD        '/data/postfix_mailbox/'

MYSQL_NAME_FIELD        name

MYSQL_MAILDIR_FIELD     maildir

MYSQL_QUOTA_FIELD       quota

MYSQL_WHERE_CLAUSE active='1'

5.安装Courier-imap
以普通用户执行下列命令
tar jxf postfix/courier-imap-4.1.3.tar.bz2
cd courier-imap-4.1.3/
./configure --enable-unicode --with-trashquota --without-ipv6
make
su
make install
make install-configure

6.安装postfixadmin

/usr/local/sbin/authdaemond start
/usr/lib/courier-imap/libexec/imapd.rc start
/usr/lib/courier-imap/libexec/pop3d.rc start

测试SMTP服务
由于在发信认证时使用的是BASE64 编码,所以要把用户名和密码转BASE64 格式
root@xxx:/home/admin# printf 'test@xxx.com\0test@xxx.com\0test' |mmencode
dGVzdEBwYWlwYWkuY29tAHRlc3RAcGFpcGFpLmNvbQB0ZXN0
root@xxx:/home/admin#  printf 'test@xxx.com' |mmencode
dGVzdEBwYWlwYWkuY29t
root@xxx:/home/admin# perl -MMIME::Base64 -e 'print encode_base64("test\@xxx.com");'
dGVzdEBwYWlwYWkuY29t
root@xxx:/home/admin# perl -MMIME::Base64 -e 'print encode_base64("test");'

$daemon_user  = 'clamav';     # (no default;  customary: vscan or amavis), -u
$daemon_group = 'clamav';     # (no default;  customary: vscan or amavis), -g

$mydomain = 'xxx.com';   # a convenient default for other settings

$MYHOME = '/data/amavis';   # a convenient default for other settings, -H
$TEMPBASE = "$MYHOME/tmp";   # working directory, needs to exist, -T

$inet_socket_port = 10024;   # listen on this local TCP port(s)

$virus_admin               = undef;  # notifications recip.
$spam_admin             = undef;

$final_virus_destiny      = D_DISCARD;
