The mail server set up: Detailed Dovecot configuration

Dovecot is a safe source of POP3 / IMAP server software, fast response and good scalability
POP3 / IMAP protocol is used when the MUA read mail from the mail server. Which, POP3 e-mail is downloaded from the mail server, and IMAP e-mail sucked remain on the server side mail management, operation directly.
Dovecot manner using PAM (Pluggable Authentication Module, pluggable authentication modules) for authentication, and verification system to identify a user, the authenticated user is allowed to receive mail from the mailbox. For dovecot RPM installed, it will automatically create the PAM file
RHEL6 system Dovecot comes with software that can be installed via yum between

[root@rhel6 ~]# yum -y install dovecot\* 
[root@rhel6 ~]# vi /etc/dovecot/dovecot.conf  
protocols = imap pop3  //使用的协议
login_trusted_networks = 192.168.0.0/24                         //设置允许连接的地址 
!include conf.d/*.conf                                          //说明conf.d下的所以conf结尾的文件均有效 
 
[root@rhel6 ~]# cat /etc/dovecot/conf.d/10-mail.conf  //设置邮件存放的路径
mail_location = mbox:~/mail:INBOX=/var/mail/%u
