/etc/postfix/virtual

[e-mail] [e-mail]

[e-mail] [e-mail]

 

要记得运行

postmap /etc/postfix/virtual生成virtual.db这样postfix才能识别。

 

cyradm创建mailbox的时候，需要user/[e-mail]这样完整的地址，如果只是cm user/info的话，

一直是报mailbox does not exist。找不到邮箱。

 

 用系统账户的话，没有必要应用saslpasswd2创建专用sasl的用户和密码

 

邮件的存储也和系统账户的mail无关

做了个小实验：

先创建系统用户

useradd -g mail -s /sbin/nologin infomy  创建一个系统用户

 

然后建立mailbox，这次建立了一个虚拟域名的mailbox,user/[e-mail] (\HasNoChildren)  

[root@calpsv04 postfix]# cyradm -u cyrus localhost

Password: 

localhost> lm

user/[e-mail] (\HasNoChildren)    

user/[e-mail] (\HasNoChildren)  

user/[e-mail] (\HasNoChildren)  

localhost> 

然后/etc/postfix/virtual的别名列表里设定[e-mail]指向那个虚拟域名的mailbox

[e-mail]   [e-mail]

 

然后postmap /etc/postfix/virtual 和postfix reload

 

在outlook里设置pop3和smtp。

outlook的登录用户名是cyradm创建的mailbox名，是lm能看到的

localhost> lm

user/[e-mail] (\HasNoChildren)  

user/[e-mail] (\HasNoChildren)  

user/[e-mail] (\HasNoChildren)     

user/[e-mail] (\HasNoChildren)   

user/[e-mail] (\HasNoChildren)   

 

用户名为虚拟域名的mailbox，能够验证通过，只是没有信。

然后发信的地方退回里了。说<[e-mail]> (expanded from <[e-mail]>): User unknown in 

    virtual alias table

 

找不到这个虚拟域名的mailbox。

然后然后/etc/postfix/virtual的别名列表里设定[e-mail]指向那个真实域名的mailbox

[e-mail]   [e-mail]

同时，outlook里的设置的的登录用户名也改成真实域名的mailbox:[e-mail]。

这样就能收到信了。

 

总结：postfix的smpt的sasl验证，只和系统账户有关，用的是系统账户的用户名和密码。telnet localhost 25验证时要AUTH PLAIN xxxxx(64base密钥)。

cyradm里创建这个系统用户的mailbox，

如：

user/[e-mail]

user/[e-mail]

用的都是infomy这个系统账户和密码来做pop3登录验证的。

虽然虚拟域名的mailbox，用系统账户也能通过验证，但是

外部网络发信到那个虚拟域名的mailbox，是不成功的。（不知道这里是不是要用虚拟mailbox方式去做设定）目前没有验证。
