POSTFIX
##1.服务器配置:(限制规则是按照查询的顺序进行的,第一条符合条件的规则被执行)
客户端主机名/地址限制 :
smtpd_client_restrictions =
check_client_access hash:/etc/postfix/access,
permit_mynetworks,reject_maps_rbl (permit_mynetworks:如果客户端的ip地址符合$mynetworks参数定义的范围则接受该客户端的连接请求;reject_maps_rbl:如果客户端的网络地址符合$maps_rbl_domains参数的值则拒绝
该客户端的连接请求)
vim access:
192.168.0.4REJECT
192.168.0REJECT
postmap access
/etc/init.d/postfix restart
实例:
westos.westos.com端:
vim access:

postmapaccess
postconf -d |grep client
postconf -e "smtpd_client_restrictions = check_client_access hash:/etc/postfix/access"
systemctl restart postfix.service
linux.linux.com端:
telnet 172.25.254.213 25
通过发件人地址进行限制 :
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/
sender
vim /etc/postfix/sender:

postmap sender
实例:

student@westos.com REJECT
postmap sender
postconf -d | grep sender
postconf -e "smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender"
systemctl restart postfix.service
linux.linux.com端:
telnet 172.25.254.213 25
通过收件人地址进行过滤 :
smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/recipient, permit_mynetworks,
reject_unauth_destination(reject_unauth_destination:不管客户端的主机名,只
要符合以下的条件, 就拒绝该客户端SMTP连接请求:
* 解析后的目标地址符合$relay_domains及其子域
* 解析后的目标地址符合$inet_interfaces、$mydestination或$virtual_maps )
vi /etc/postfix/recipient:
user@example.com
DISCARDED
postmap recipient
实例:
westos.westos.com端:
vim recip
student@westos.comREJECT
postmap recip
postconf -d | grep recip
postconf -e "smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/recip"
systemctl restart postfix.service

豆腐块(dovecot)
##1.mutt的创建与使用
westos.westos.com端:
yum install dovecot -y
cd /etc/dovecot/
vim dovecot.conf
24 protocols = imap pop3 lmtp
49 disable_plaintext_auth = no
[root@westos conf.d]# vim 10-mail.conf
30 mail_location = mbox:~/mail:INBOX=/var/mail/%u
[root@westos skel]# mkdir mail/.imap/ -p
[root@westos skel]# touch mail/.imap/INBOX
[root@westos dovecot]# useradd lee
[root@westos dovecot]# passwd lee
##先创建目录后建立的新用户会自动生成该文件,不必切换到该用户再自行创建
linux.linux.com端:
yum install mutt -y
##2.雷鸟的创建与使用
westos.westos.com端;
[root@westos dovecot]# vim /etc/dovecot/dovecot.conf
49 login_trusted_networks = 0.0.0.0/0
[root@westos dovecot]# systemctl restart dovecot.service
linux.linux.com端:
[root@linux postfix]# cd /mnt/
[root@linux mnt]# ls
thunderbird-45.5.1.tar.bz2
[root@linux mnt]# tar jxf thunderbird-45.5.1.tar.bz2
[root@linux mnt]# cd thunderbird/
[root@linux thunderbird]# ./thunderbird
