1. 安裝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
開始安裝
make
make install
一路enter直到安裝完成
2.安裝 vm-pop3d (為了收郵件)
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 啟動pop3
3.配置安裝完的postfix配置目錄在/etc/postfix下,主要配置main.cf,粗體部分是我修改過的,mail.jq.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.jq.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
啟動postfix: postfix start
注意iptables要開放25和110端口,hosts.allow加入vm-pop3d:all
此時應該就可以用foxmail收發郵件了,我測試的時候一直提示輸入密碼,輸入系統密碼又不對看日志cat /var/log/maillog
Dec 3 09:18:08 zhangwenhao1 vm-pop3d[12632]: Couldn't open password file: /etc/virtual/mail.jq.com/passwd
之后
mkdir -p /etc/virtual/mail.jq.com/ ln -s /etc/shadow /etc/virtual/mail.jq.com/passwd
再次測試,發送接收郵件成功,這里是使用系統的帳戶,也可以自己新建虛擬賬戶,利用apache的htpasswd
/usr/local/apache2/bin/htpasswd -c /etc/virtual/mail.jq.com/passwd jq
輸入密碼,就可以使用虛擬帳戶收發郵件了
