我正在配置Postfix，通过telnet和SMTP验证时，我得到了状态反弹错误，未知用户:
Error log:
后缀/本地[18718]:4590D7DC0A51:to=，中继=本地，延迟=9.8，延迟=9.8/0.01/0/0.04，dsn=5.1.1，状态=已跳转(未知用户:"myuser")
"myuser"已存在，但具有完整的域名:myuser@mydomain.com.
User Validation:
postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
输出是:"1"-所以我想它是好的.
My postfix Configuration:
root# postconf -n:
