E-MAIL SERVER架設(2016/04/06)

E-MAIL SERVER架設雖然有弄完,可是郵件傳不出去一直顯示removed,因此後面就沒有辦法在做下去囉~

首先一樣要安裝Postfix套件:#yum -y install postfix dovecot

編修目錄檔:

#vim /etc/postfix/main.cf
myhostname = mail.example.com
mydomain = example.com
myorigin = $mydomain
mynetworks_style = class
mynetworks = 127.0.0.0/8, 192.168.100.0/24(打本機網段即可)

inet_interfaces = all
mydestination = $mydomain, $myhostname, localhost.$mydomain, localhost
mail_spool_directory = /var/mail

home_mailbox = Maildir/
mailbox_size_limit = 0  #原設定參數沒有
message_size_limit = 0  #請自己加上即可

換編修這個目錄檔:

#vim /etc/dovecot/dovecot.conf
protocols = imap pop3
編修設定檔: 
#vim /etc/dovecot/conf.d/10-mail.conf
mail_location = mbox:~/mail:INBOX=/var/mail/%u

開啟防火牆服務:
#firewall-cmd --permanent --add-service=smtp
#firewall-cmd --permanent --add-port=110/tcp
#firewall-cmd --permanent --add-port=143/tcp
#firewall-cmd --reload


設定 SELinux ：
#setsebool -P postfix_local_write_mail_spool on


啟動 smtp 與 imap 的服務：
#systemctl enable postfix
#systemctl enable dovecot
#systemctl start postfix
#systemctl start dovecot

檢測mail可否發送出去(我就是掛在這邊XD):
#mail student@mail.example.com
Subject:  test
Hello World!
.(PS "."是結束的意思)
查看一下的記錄:
#tail /var/log/maillog
