快速配置postfix

在centos6.0上系统默认已安装了postfix和sasl
1.vi /etc/postfix/main.cf

myhostname=mail.c1gstudio.com
mydomain=c1gstudio.com
myorigin=$mydomain
inet_interfaces=all
mydestintion=$myhostname,localhost,$mydomain,localhost
mynetworks=192.168.100.0/24,127.0.0.0/8

#################CYRUS-SASL###################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_sasl_application_name = smtpd
smtpd_banner = $myhostname ESMTP,Warning: Version not Available!
smtpd_reject_unlisted_recipient = no

2.vim /etc/sasl2/smtpd.conf

pwcheck_method: saslauthd
mech_list: plain login

3.iptables

iptables -A INPUT -p tcp –dport 25 -j ACCEPT

service iptables save

4.自动运行

chkconfig postfix on
chkconfig saslauthd on

6.添加smtp认证用户
===================
使用shadow认证
[[email protected] ~]# groupadd mailuser
[[email protected] ~]# adduser -g mailuser -s /sbin/nologin service
[[email protected] ~]# passwd service
Changing password for user service.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[[email protected] ~]#

检查是否可以通过认证
[[email protected] ~]# testsaslauthd -u service -p 123456
0: OK “Success.”

生成base64备用
[[email protected] ~]#

perl -MMIME::Base64 -e ‘print encode_base64(“service”);’

c2VydmljZQ==
[[email protected] ~]#

perl -MMIME::Base64 -e ‘print encode_base64(“123456”);’

MTIzNDU2

7.测试
[[email protected] ~]# telnet localhost 25
