Perdition + Postfix...简单的 POP3 Proxy 邮件服务器

hata_ph

今天在 centos 6 里安装 perdition + postfix 来做一个简单的 POP3 Proxy 邮件服务器

把下面的腳本保存為 home_horms_perdition.repo 到 /etc/yum.repos.d

1. [home_horms_perdition]
   
2. name=Perdition: Mail Retrieval Proxy (CentOS_CentOS-6)
   
3. type=rpm-md
   
4. baseurl=http://download.opensuse.org/repositories/home:/horms:/perdition/CentOS_CentOS-6/
   
5. gpgcheck=1
   
6. gpgkey=http://download.opensuse.org/repositories/home:/horms:/perdition/CentOS_CentOS-6/repodata/repomd.xml.key
   
7. enabled=1
   

复制代码

通過 yum 安裝的 perdition

1. yum install perdition

复制代码

編輯/ etc / sysconfig/perdition（只使用POP3服務）

1. RUN_PERDITION=yes
   
2. POP3=yes #ou yes
   
3. POP3S=no #ou yes
   
4. IMAP4=no #ou yes
   
5. IMAP4S=no #ou no
   

复制代码

把 /etc/perdition/ perdition.conf

做一個副本
，並命名它為perdition.pop3.conf

1. cp /etc/perdition/perdition.conf /etc/perdition/perdition.pop3.conf

复制代码

編輯
/etc/perdition/perdition.pop3.conf

1. outgoing_server $ SERVER $ #use hostname or IP
   
2. protocol pop3
   
3. listen_port 110
   
4. outgoing_port 110
   
5. debug # optional for debuging
   
6. connection_logging # optional for debugging

安装 postfix

1. yum install postfix

复制代码

编辑 /etc/postfix /main.cf 文件

1. # Set this to your server's fully qualified domain name.
   
2. # If you don't have a internet domain name,
   
3. # use the default or your email addy's domain - it'll keep
   
4. # postfix from generating warnings all the time in the logs
   
5. mydomain = local.domain
   
6. myhostname = host.local.domain
   
7. inet_interfaces = all
   
8. 
   
9. # Set this to your email provider's smtp server.
   
10. # A lot of ISP's (ie. Cox) block the default port 25
    
11. # for home users to prevent spamming.  So we'll use port 80
    
12. relayhost = $smtp_relay_server$
    
13. 
    
14. smtpd_sasl_path = smtpd
    
15. smtp_sasl_type = cyrus
    

复制代码

禁用防火墙

1. chkconfig iptables off
   
2. chkconfig ip6tables off

按照以下设置，如果您的SMTP中继服务器需要身份验证。

安装 cyrus-sasl-plain

1. yum install cyrus-sasl-plain

复制代码

编辑的 /etc/postfix / main.cf 文件

1. # Set this to your server's fully qualified domain name.
   
2. # If you don't have a internet domain name,
   
3. # use the default or your email addy's domain - it'll keep
   
4. # postfix from generating warnings all the time in the logs
   
5. mydomain = local.domain
   
6. myhostname = host.local.domain
   
7. inet_interfaces = all
   
8. 
   
9. # Set this to your email provider's smtp server.
   
10. # A lot of ISP's (ie. Cox) block the default port 25
    
11. # for home users to prevent spamming.  So we'll use port 80
    
12. relayhost = yourisp.smtp.servername:80
    
13. 
    
14. smtpd_sasl_auth_enable = yes
    
15. smtpd_sasl_path = smtpd
    
16. smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
    
17. smtp_sasl_type = cyrus
    
18. smtp_sasl_auth_enable = yes
    
19. 
    
20. # optional: necessary if email provider uses load balancing and
    
21. # forwards emails to another smtp server
    
22. # for delivery (ie: smtp.yahoo.com --> smtp.phx.1.yahoo.com)
    
23. smtp_cname_overrides_servername = no
    
24. 
    
25. # optional: necessary if email provider
    
26. # requires passwords sent in clear text
    
27. smtp_sasl_security_options = noanonymous
    

复制代码

添加以下行到  /etc/postfix/sasl_passwd

1. yourisp.smtp.servername:80 username:password

复制代码

把 sasl_passwd
生成一个后缀查找表

1. postmap hash:/etc/postfix/sasl_passwd

复制代码

测试查找表，如果一切都很好，那么下面将返回指定的用 username:password

1. postmap -q yourisp.smtp.servername:80 /etc/postfix/sasl_passwd

复制代码

确保的 sasl_passwd 和 sasl_passwd.db 文件只有 root 可读/写

1. chmod 600 /etc/postfix/sasl_passwd
   
2. chmod 600 /etc/postfix/sasl_passwd.db
   

复制代码

用 sendmail 测试它

1. sendmail email@example.com
   
2. Postfix is good to go.
   
3. .

可选：启用防火墙

1. chkconfig iptables on

复制代码

编辑 /etc/sysconfig/iptables, 允许 pop3/pop3s 和 SMTP/SMTPS 端口

1. # smtp/smtp3
   
2. -A INPUT –p tcp –m multiport –-dport 25,465 –j ACCEPT
   
3. # pop3/pop3s
   
4. -A INPUT –p tcp –m multiport –-dport 110,995 –j ACCEPT
