更改上面的xxxx.com为实际的邮件域名 /Maildir/maildata存储邮件文件 /Maildir/mailconf存储用户信息 需要设定postfix的virtual mail box的信息，和dovecot的users的信息

vi /Maildir/mailconf/vmailbox [email protected] xxx.com/aaa/Maildir/

用doveadm pw生成密码，写入下面的文件 vi /Maildir/mailconf/users [email protected]:{CRAM-MD5}4c4f1d6305e5505e66630ded6bf16a9b05b28f73377f3f68921076f20479937c

/etc/pki/tls/certs有服务器的证书
