-安裝套件

# yum install postfix
# yum install dovecot
# yum install cyrus-sasl cyrus-sasl-md5
 

-編輯登入認證方式

# vi /etc/sysconfig/saslauthd
MECH=shadow
 

-編輯 Dovecot 設定

編輯文件 /etc/dovecot/conf.d/10-master.conf

# vi /etc/dovecot/conf.d/10-master.conf
unix_listener auth-userdb {
#mode = 0666
#user =
#group =
}

# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
mode = 0666
user = postfix
group = postfix
}
 

編輯文件 /etc/dovecot/conf.d/10-auth.conf

# vi /etc/dovecot/conf.d/10-auth.conf
disable_plaintext_auth = no
auth_mechanisms = plain login
 

編輯文件 /etc/dovecot/conf.d/10-ssl.conf

# vi /etc/dovecot/conf.d/10-ssl.conf
ssl=no
 

編輯文件 /etc/dovecot/dovecot.conf

# vi /etc/dovecot/dovecot.conf
protocols = pop3
 

編輯文件 /etc/dovecot/conf.d/10-mail.conf

# vi /etc/dovecot/conf.d/10-mail.conf
#mail_location = maildir:~/Maildir
mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u
 

-編輯 Postfix 設定

# vi /etc/postfix/main.cf

在最後面加入以下的內容

( Esc G = 移至該檔案的最後一列)

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
 

-設定 SELinux

#setsebool -P postfix_local_write_mail_spool on
 

-設定防火牆

#firewall-cmd --permanent --add-service=smtp
#firewall-cmd --permanent --add-service=pop3
#firewall-cmd --reload
 

-啟動服務

# systemctl enable saslauthd.service
# systemctl restart saslauthd.service
# systemctl status saslauthd.service
 
# systemctl restart dovecot.service
# systemctl status dovecot.service
 
# systemctl restart postfix.service
# systemctl status postfix.service
 

-測試

# telnet localhost 25
ehlo localhost
 

如果有出現「AUTH=PLAIN LOGIN」，應該大致上沒有問題
