我正在 ubuntu 20.04 中使用 postfix+dovecot+mysql 设置电子邮件服务器
我在尝试验证用户时遇到问题。它没有收到 %d 配置变量中的域信息（https://doc.dovecot.org/configuration_manual/config_file/config_variables/）
这是我的 /etc/dovecot/dovecot-sql.conf.ext 文件：
driver = mysql
connect = host=127.0.0.1 dbname=mail user=mail password=**********
default_pass_scheme = SHA512-CRYPT
user_query = select '/home/' home, 5000 id, 5000 from virtual_users u join virtual_domains d on u.domain_id=d.id WHERE u.email='%n' and d.name='%d'
password_query = select u.email as user, d.name as domain, password from virtual_users u join virtual_domains d on u.domain_id=d.id WHERE u.email='%n' and d.name='%d'
iterate_query = select u.email as user, d.name as domain, password from virtual_users u join virtual_domains d on u.domain_id=d.id
这是我在日志中看到的内容：

我是否在其他配置文件中遗漏了某些内容？我做错了什么？
答案1
我找到了问题所在。在 /etc/dovecot/conf.d/10-auth.conf 中检查此设置并确保其值为 %u
auth_username_format=%u
