本教程不使用mysql存储用户名和密码,只作为smtp服务,
需要安装dns,详情见 点击打开链接http://blog.youkuaiyun.com/zhidao_wenge/article/details/69982350
一、安装软件:
yum install postfix
yum install cyrus*
不卸掉下面两个会报错(因为不使用mysql)
rmp -e cyrussaslldap
rmp -e cyrussaslsql
二、编辑配置文件
编辑:/etc/postfix/main.cf (详情介绍 点击打开链接, 点击打开链接)
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
myhostname = test01v.jira.net
mydomain = jira.com
myorigin = $mydomain
inet_interfaces = all
local_recipient_maps =
unknown_local_recipient_reject_code = 550
mynetworks = 10.0.0.0/24
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
home_mailbox = Maildir/
smtpd_banner = $myhostname ESMTP unknow
debug_peer_level = 2
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man
sample_directory = /usr/share/doc/postfix-2.6.6/samples
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
#增加以下
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated, reject_unauth_destination
编辑:vim /etc/sasl2/smtpd.conf (详情介绍点击打开链接)
pwcheck_method: auxprop
auxprop_plugin: sasldb
mech_list: plain login CRAM-MD5 DIGEST-MD5
log_level: 3
编辑:vim /etc/sysconfig/saslauthd
SOCKETDIR=/var/run/saslauthd
#MECH=pam
FLAGS=sasldb
三、修改权限和启动
chmod 755 /etc/sasldb2
service postfix restart
service saslauthd restart
service cyrus-imapd restart
日志 在 /var/log/message 和 /var/log/mailsend 可以查看
四、修改
alternatives --display mta 可以查看默认发邮件程序,如果不是/usr/sbin/sendmail.postfix,可以用个下面命令修改
alternatives --config mta
五、增加用户:
saslpasswd2 -c -u `postconf -h mydomain` test
会让输入两次密码,会产生test@mydomain,安装之前的配置会产生 test@jira.com
查看用户名:sasldblistusers2
六、测试:(详情见:点击打开链接)
(echo -n xxx | openssl base64 -a 会输出xxx的64位编码)telnet测试用base64加密
telnet 127.0.0.1 25
AUTH LOGIN # 后面依次输入 test@jira.com 和密码的 base64加密信息
如果验证 成功了,其他服务器可以连接改smtp,进行发邮件了
