最简单的邮件服务器postfix安装(原创)
1. 安装postfix
   tar -zxf postfix-2.4.6.tar.gz
   cd postfix-2.4.6
   mv /usr/sbin/sendmail /usr/sbin/sendmail.OFF
   mv /usr/bin/newaliases /usr/bin/newaliases.OFF
   mv /usr/bin/mailq /usr/bin/mailq.OFF
   chmod 755 /usr/sbin/sendmail.OFF /usr/bin/newaliases.OFF /usr/bin/mailq.OFF
   vi /etc/passwd:
           postfix:*:12345:12345:postfix:/no/where:/no/shell
   vi  /etc/group:
           postfix:*:12345:
或者用命令
    groupadd postfix -c 12345
    useradd -u 12345 -g 12345 -c postfix -d/dev/null -s/bin/false postfix
    groupadd -c 54321 postdrop
开始安装
  make
  make install
一路enter直到安装完成
2.安装 vm-pop3d (为了收邮件)
  tar zxvf vm-pop3d-1.1.6.tar.gz
  cd vm-pop3d-1.1.6
  ./configure --prefix=/usr/local/pop3 --enable-pam  --enable-virtual --enable-ip-based-virtual
  make
  make install
vi /etc/xinetd.d/pop3
# default: off
# description: The rsync server is a good addition to an ftp server, as it \
#       allows crc checksumming etc.
service pop3 {      
disable = no      
socket_type     = stream      
wait            = no      
protocol        = tcp      
user            = root      
server          = /usr/local/pop3/sbin/vm-pop3d
}
然后就service xinetd start 启动pop3
3.配置安装完的postfix配置目录在/etc/postfix下,主要配置main.cf,粗体部分是我修改过的,mail.lzz.com配hosts
vi /etc/postfix/main.cf
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
myhostname = mail.lzz.com
inet_interfaces = all
mydestination = $myhostname
unknown_local_recipient_reject_code = 550
mynetworks = 192.168.0.0/16, 127.0.0.0/8, 0.0.0.0/0
alias_maps = hash:/etc/aliases   
alias_database = hash:/etc/aliases
local_recipient_maps = $alias_maps unix:passwd.byname   
debug_peer_level = 2   
debugger_command =        PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin         
xxgdb $daemon_directory/$process_name $process_id & sleep 5   
sendmail_path = /usr/sbin/sendmail   
newaliases_path = /usr/bin/newaliases   
mailq_path = /usr/bin/mailq   
setgid_group = postdrop   
html_directory = no   
manpage_directory = /usr/local/man   
sample_directory = /etc/postfix   
readme_directory = no
启动postfix: postfix start
注意iptables要开放25和110端口,hosts.allow加入vm-pop3d:all
此时应该就可以用foxmail收发邮件了,我测试的时候一直提示输入密码,输入系统密码又不对看日志cat /var/log/maillog
  Dec  3 09:18:08 zhangwenhao1 vm-pop3d[12632]: Couldn't open password file: /etc/virtual/mail.lzz.com/passwd
之后
  mkdir -p /etc/virtual/mail.lzz.com/ ln -s /etc/shadow /etc/virtual/mail.lzz.com/passwd
再次测试,发送接收邮件成功,这里是使用系统的帐户,也可以自己新建虚拟账户,利用apache的htpasswd
/usr/local/apache2/bin/htpasswd -c /etc/virtual/mail.lzz.com/passwd lzz
输入密码,就可以使用虚拟帐户收发邮件了
