Linux中mail邮件服务postfix故障解决方法

故障点

Llnux做好邮箱服务后不能与Windows的outlook连接或者登录提示出错。

可以看到我在Windows上的outlook添加的我自己的服务器配置的mail信息

显示任务：登录到接收邮件服务器（P0P3）失败
发送测试电子邮件信息失败

错误：登录到接收邮件服务器（POP3）：找不到电子邮件服务器。请在账户属性中验证服务器信息。
发送到测试电子邮件消息：找不到电子邮件服务器。请在账户属性中验证服务器信息。

故障分析

第一个问题是登录问题，第一步你应该测试IP是否ping通，第二步看端口是否开启，防火墙是否添加规则或者关闭，selinux是否添加或者关闭了。最后看配置是否开启pop3并且服务重启。
第二个问题是测试过程证明已经登录，但是发送有问题，一般出现在配置上，有的的右键服务要验证安全性，然而你没有关闭或者配置相应的从而出现问题。

划重点-postfix全过程-无毛病操作

做邮箱需要DNS服务的支持，做好对邮箱的支持然后开始进行邮箱服务的安装

1 2	yum install postfix 可能会默认安装 yum install dovecot -y

cd /etc/postfix
vim main.cf
76 myhostname = mail.jnds.com
83 mydomain = jnds.com
99 myorigin = $mydomain
116 inet_interfaces = all
165 mydestination = $myhostname, $mydomain

cd conf.d/

vim 10-ssl.conf

vim 10-auth.conf
10 disable_plaintext_auth = no

su - boss 用户名是你邮箱的用户名
mkdir -p mail/.imap/INBOX 如果没有这个出错会提示接收不了
exit

以上可以完美解决mail连接Windows上的Outlook不能连接或者不能登录的问题。
