第一步:(Windows本地安装foxmail测试两账号成功互收发)
yum install postfix dovecot cyrus-sasl cyrus-sasl-plain cyrus-sasl-md5

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).

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)

第三步:(加入mysql实现虚拟用户收发邮件)
