增加用户:

userdel test1(删除用户)

groupdel test1(删除用户组)

useradd test2

echo 'test2' |passwd --stdin test2

useradd test3

echo 'test3' |passwd --stdin test3

vi /etc/passwd

test2:x:1001:2001::/home/test2:/sbin/nologin(不能登录系统)

test3:x:1002:2002::/home/test3:/sbin/nologin


测试1:

# telnet mail.wc365.com 25  

Trying 192.168.1.2...

Connected to mail.wc365.com (192.168.1.2).

Escape character is '^]'.

220 mail.yjw.com ESMTP Postfix

EHLO 163.com(只需要输入该行即可,一下都是现实信息)

250-mail.wc365.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-AUTH LOGIN PLAIN

250-AUTH=LOGIN PLAIN

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

quit(输入退出命令)

221 2.0.0 Bye

Connection closed by foreign host.


测试2:

echo "this is a test mail" | mail -s mailname [email protected](查看QQ邮箱是否有新邮件)


测试3:

Windows安装的foxmail客户端

新建--》手动设置--》配置如下--》创建--》确定(应用)--》邮件成功互收发即可

接受服务器类型:POP3

    邮件账号:[email protected]

      密码: 123456

   POP服务器:mail.wc365.com    110

  SMTP服务器:mail.wc365.com     25


检查3:

默认的MTA是sendmail。所以我们需要键入以下命令更新MTA为Postfix

/usr/sbin/alternatives --set mta /usr/sbin/sendmail.postfix

再次检查看MTA是不是改为Postfix了

alternatives --display mta


报错1:postfix/sendmail[13310]: fatal: parameter inet_interfaces: no local interface found for ::1

解决1:

vi /etc/postfix/main.cf

#inet_protocols = all(注释掉该行)

#wc add1

inet_protocols = ipv4

systemctl start postfix(检查端口号查看是否起来)


报错2:ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)

解决2:ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock


报错3:dovecot: pop3-login: Aborted login (auth failed, 1 attempts in 4 secs

解决3:一般都是权限问题

ll /var/mail或者ll /home


报错4:error: mailbox_size_limit is smaller than message_size_limit

解决4:message_size_limit = 5120000(数值改小即可)


报错5:useradd: group wc exists - if you want to add this user to that group, use -g.

解决5:这是因为只删除了用户,用户组没有删除的原因

userdel test1(删除用户)

groupdel test1(删除用户组)
