linux配置电子邮件传输（二）

下面我们做一些邮件客户端的配置

1.邮件客户端的访问控制

1.限制远程发送

在westos-mail主机上

[root@westos-mail ~]# postconf -d | grep client  [root@westos-mail ~]# postconf -e "smtpd_client_restrictions = check_client_access hash:/etc/postfix/access"[root@westos-mail ~]# vim /etc/postfix/access 172.25.254.48    REJECT[root@westos-mail ~]# vim /etc/postfix/main.cf smtpd_client_restrictions = check_client_access hash:/etc/postfix/access  #查看是否变色  [root@westos-mail ~]# postmap /etc/postfix/access   对文件加密[root@westos-mail ~]# cd /etc/postfix/[root@westos-mail postfix]# lsaccess     canonical  header_checks  master.cf  relocated  virtualaccess.db  generic    main.cf        moreuser   transport    ##.db文件为真正的加密文件[root@westos-mail ~]# systemctl restart postfix.service 测试：[root@foundation48 ~]# telnet 172.25.254.10 25Trying 172.25.254.10...Connected to 172.25.254.10.Escape character is '^]'.220 westos-mail.westos.com ESMTP Postfixmail from:[e-mail]250 2.1.0 Okrcpt to:[e-mail]554 5.7.1 <unknown[172.25.254.48]>: Client host rejected: Access denied    ##主机拒绝接收

2.限制用户发送

[root@westos-mail postfix]# postconf -d | grep sender[root@westos-mail postfix]# postconf -e "smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender"[root@westos-mail postfix]# vim /etc/postfix/[e-mail] REJECT[root@westos-mail postfix]# postmap /etc/postfix/sender [root@westos-mail postfix]# cd /etc/postfix/[root@westos-mail postfix]# lsaccess     canonical  header_checks  master.cf  relocated  sender.db  virtualaccess.db  generic    main.cf        moreuser   sender     transport[root@westos-mail postfix]# systemctl restart postfix.service 

测试：

[root@foundation48 ~]# telnet 172.25.254.10 25Trying 172.25.254.10...Connected to 172.25.254.10.Escape character is '^]'.220 westos-mail.westos.com ESMTP Postfixmail from:[e-mail]250 2.1.0 Okrcpt to:[e-mail]554 5.7.1 <[e-mail]>: Sender address rejected: Access denied

3.限制用户接收

[root@westos-mail postfix]# postconf -d | grep rec[root@westos-mail postfix]# postconf -e "smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/recip"[root@westos-mail postfix]# vim /etc/postfix/[e-mail] REJECT[root@westos-mail postfix]# postmap /etc/postfix/recip[root@westos-mail postfix]# cd /etc/postfix/[root@westos-mail postfix]# lsaccess     generic        master.cf  recip.db   sender.dbaccess.db  header_checks  moreuser   relocated  transportcanonical  main.cf        recip      sender     virtual[root@westos-mail postfix]# systemctl restart postfix.service 

测试：

[root@foundation48 ~]# telnet 172.25.254.10 25Trying 172.25.254.10...Connected to 172.25.254.10.Escape character is '^]'.220 westos-mail.westos.com ESMTP Postfixmail from:[e-mail]250 2.1.0 Okrcpt to:[e-mail]554 5.7.1 <[e-mail]>: Recipient address rejected: Access denied

出战地址伪装

配置dovecot

1.给定用户

用来提供收件协议
pop3 110 ##相应的端口
imap 143
imaps 993
pop3s 995

[root@westos-mail ~]# yum install dovecot -y[root@westos-mail ~]# vim /etc/dovecot/dovecot.conf 24 protocols = imap pop3 lmtp     协议 48 login_trusted_networks = 0.0.0.0/0 49 disable_plaintext_auth = no[root@westos-mail ~]# vim /etc/dovecot/conf.d/10-mail.conf 30 mail_location = mbox:~/mail:INBOX=/var/mail/%u[root@westos-mail ~]# systemctl restart dovecot

测试：

[root@westos-mail ~]# su - westos[westos@westos-mail ~]$ mkdir -p mail/.imap/[westos@westos-mail ~]$ touch mail/.imap/INBOX[root@westos-mail ~]# mkdir -p /etc/skel/mail/.imap [root@westos-mail ~]# touch /etc/skel/mail/.imap/INBOX[root@westos-mail ~]# yum install mutt  ##安装服务[root@westos-mail ~]# mutt -f pop://westos@172.25.254.120
