本文主要介紹的是在CentOS 7.2安裝部署郵件服務器(Postfix)的相關內容，分享出來供大家參考學習，下面來看看詳細的介紹：
Postfix 是一種電子郵件服務器，它是由任職于IBM華生研究中心（T.J. Watson Research Center）的荷蘭籍研究員Wietse Venema為了改良sendmail郵件服務器而產生的。最早在1990年代晚期出現，是一個開放源代碼的軟件。
注意：以下所有配置的命名都是根據主機的hostname變量來配置的，如果hostname更換了的話，需要重新生成證書。
生成ssl證書
1、生成證書的腳本代碼
以hostname為命名生成證書，運行腳本后需輸入四次相同密碼(密碼須包含數字和字母)
#!/bin/shrm -rf $(hostname).*openssl genrsa -des3 -out $(hostname).key 1024SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$(hostname)"openssl req -new -subj $SUBJECT -key $(hostname).key -out $(hostname).csrmv $(hostname).key $(hostname).origin.keyopenssl rsa -in $(hostname).origin.key -out $(hostname).keyopenssl x509 -req -days 3650 -in $(hostname).csr -signkey $(hostname).key -out $(hostname).crtcp $(hostname).crt /etc/pki/tls/certs/$(hostname).crtcp $(hostname).key /etc/pki/tls/certs/$(hostname).keyecho "the key path:/etc/pki/tls/certs/$(hostname).key"echo "the crt path:/etc/pki/tls/certs/$(hostname).crt"rm -rf $(hostname).*
Postfix安裝及配置
安裝
yum -y install postfix
配置
vim /etc/postfix/main.cf

Dovecot 安裝及配置
安裝
yum -y install dovecot
配置
vim /etc/dovecot/dovecot.conf
# line 24: uncommentprotocols = imap pop3 lmtp# line 30: uncomment and change ( if not use IPv6 )listen = *
vim /etc/dovecot/conf.d/10-auth.conf
# line 10: uncomment and change ( allow plain text auth )disable_plaintext_auth = no# line 100: addauth_mechanisms = plain login
vim /etc/dovecot/conf.d/10-mail.conf
# line 30: uncomment and addmail_location = maildir:~/Maildir
vim /etc/dovecot/conf.d/10-master.conf
# line 96-98: uncomment and add like follows# Postfix smtp-authunix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix}vim /etc/dovecot/conf.d/10-ssl.conf
# line 8: changessl = yes# line 14,15: specify certificatesssl_cert = </etc/pki/tls/certs/$(hostname).crtssl_key = </etc/pki/tls/certs/$(hostname).key
運行
systemctl restart postfixsystemctl enable postfixsystemctl start dovecotsystemctl enable dovecotfirewall-cmd --add-service=smtp --permanentfirewall-cmd --add-port={110/tcp,143/tcp} --permanentfirewall-cmd --add-service={pop3s,imaps} --permanentfirewall-cmd --add-port=465/tcp --permanentfirewall-cmd --reload郵件日志報告pflogsumm
安裝
yum -y install postfix-perl-scripts
查看
perl /usr/sbin/pflogsumm -d yesterday /var/log/maillog
每天1:00AM 定時發送郵件日志摘要到根
crontab -e00 01 * * * perl /usr/sbin/pflogsumm -e -d yesterday /var/log/maillog | mail -s 'Logwatch for Postfix' root
