1.安装 postfix-2.9.6-pgsql，默认带dovecot的认证方式（SMTP）
server:/home/xisxy$ sudo pkg_add postfix-2.9.6-pgsql.tgz
-> Creating /etc/mailer.conf.postfix
-> Creating Postfix spool directory and chroot area under /var/spool/postfix
-> Creating Postfix data directory under /var/postfix
+---------------
| Configuration files have been installed in /etc/postfix.
| Please update these files to meet your needs.
+---------------
postfix-2.9.6-pgsql: ok
The following new rcscripts were installed: /etc/rc.d/postfix
See rc.d(8) for details.
--- +postfix-2.9.6-pgsql -------------------
Postfix can be set up to replace sendmail entirely. Please read the
documentation at file:/usr/local/share/doc/postfix/html/index.html or
http://www.postfix.org/ carefully before you decide to do this!
To replace sendmail with Postfix you have to install a new mailer.conf
using the following command:
/usr/local/sbin/postfix-enable
If you want to restore sendmail, this is done using the following command:
/usr/local/sbin/postfix-disable
server:/home/xisxy$ sudo /usr/local/sbin/postfix-enable
old /etc/mailer.conf saved as /etc/mailer.conf.pre-postfix
postfix /etc/mailer.conf enabled
NOTE: do not forget to add sendmail_flags=NO to
/etc/rc.conf.local to disable sendmail.
NOTE: do not forget to add "-a /var/spool/postfix/dev/log" to
syslogd_flags in /etc/rc.conf.local and restart syslogd.
NOTE: do not forget to add postfix to pkg_scripts in
/etc/rc.conf.local to start postfix automatically.
NOTE: do not forget to remove the "sendmail clientmqueue runner"
from root's crontab.
开启postfix替换到自带的sendmail
server:/home/xisxy$ sudo /usr/local/sbin/postfix-enable
最终的/etc/rc.conf.local，内容如下：
sendmail_flags=NO
syslogd_flags="-a /var/spool/postfix/dev/log"
nginx_flags=""
pkg_scripts="postgresql php_fpm postfix "
server:/home/xisxy$ sudo crontab -e
# sendmail clientmqueue runner
#*/30 * * * * /usr/sbin/sendmail -L sm-msp-queue -Ac -q
重启系统，让postfix完全替换掉sendmail
server:/home/xisxy$ sudo reboot
2.配置 postfix
准备工作
新建一个不能登录系统的帐户vmail,作为postfix虚拟用户在系统中的身份
server:/home/xisxy$ sudo useradd -m -d /var/vmail/ -s /sbin/nologin -u 3000 -g=uid vmail
用postfixadmin生成测试域名和测试用户
test.com
[email protected]
生成postfix信息在postgresql数据库中的查询表，只建了三个常用的映射表，如要用到更多功能可再手动加
简单的脚本如下：
server:/home/xisxy$vi create_pgsql_maps.sh
#!/bin/sh
cd /etc/postfix
PGPW="Your_DB_password"
PGUSER="postfixdbm"
PGDB="postfixdb"
HOST="127.0.0.1"
cat -user = $PGUSER
password = $PGPW
hosts = $HOST
dbname = $PGDB
query = Select goto From alias Where address='%s' and active =true
EOF
cat -user = $PGUSER
password = $PGPW
hosts = $HOST
dbname = $PGDB
query = Select domain from domain where domain='%s' and backupmx = false and active=true
EOF
cat -user = $PGUSER
password = $PGPW
hosts = $HOST
dbname = $PGDB
query = Select maildir from mailbox where username='%s' and active=true
EOF
server:/home/xisxy$ chmod +x create_pgsql_maps.sh
server:/home/xisxy$ sudo create_pgsql_maps.sh
查看效果
server:/home/xisxy$ cd /etc/postfix
server:/etc/postfix$ ls |grep maps
pgsql_virtual_alias_maps.cf
pgsql_virtual_domains_maps.cf
pgsql_virtual_mailbox_maps.cf
验证能否查询到正确结果：
#postmap -q [email protected] pgsql:/etc/postfix/pgsq_virtual_alias_maps.cf
[email protected]
server:/etc/postfix$ sudo vi main.cn
在最后添加如下类似内容
myhostname = mail.test.com
mydomain = test.com
myorigin = $mydomain
inet_interfaces = all
mynetworks = 127.0.0.0/8
alias_maps = hash:/etc/postfix/aliases
home_mailbox = Maildir/
mailbox_size_limit = 51200000
virtual_mailbox_limit = 51200000
message_size_limit = 10240000
virtual_uid_maps = static:3000
virtual_gid_maps = static:3000
virtual_mailbox_base = /var/vmail/
virtual_alias_maps = $alias_maps,proxy:pgsql:/etc/postfix/pgsql_virtual_alias_maps.cf
virtual_mailbox_maps = proxy:pgsql:/etc/postfix/pgsql_virtual_mailbox_maps.cf
virtual_mailbox_domains = proxy:pgsql:/etc/postfix/pgsql_virtual_domains_maps.cf
国加入了alias_maps = hash:/etc/postfix/aliases，使aliases列表生效
server:/etc/postfix$ sudo postalias /etc/postfix/aliases
posfix生效新配置文件
server:/etc/postfix$ sudo postfix reload
发测试信
server:/etc/postfix$ mail [email protected]
