我的 MySQL Courier + Postfix 电子邮件服务器有问题

这是错误日志：

warning: mysql:/etc/postfix/mysql-virtual_domains.cf: query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'virtual FROM `domains` WHERE domain='domain.example'' at line 1

和代码mysql-virtual_domains.cf：

user = mail_admin
password = mypassword
dbname = mail
query = SELECT domain AS virtual FROM `domains` WHERE domain='%s'
hosts = 127.0.0.1

该怎么办？

我尝试让邮件服务器在 PostgreSQL 上工作，但出现以下错误：

Apr 16 20:48:57 alm authdaemond: PGSQL_CONNECTION could not be established
Apr 16 20:48:57 alm authdaemond: FATAL:  database "mail_admin" does not exist.

我遵循本手册并尝试以某种方式使其在 PostgreSQL 而不是 MySQL 中工作： https ://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-ubuntu-14.04- lts

是的，我有数据库邮件，它是用户 mail_admin，并且该用户可以访问邮件数据库。

这是更多错误日志。

将系统从 14.04 升级到 16.04 后，我无法安装 MySQL

我试图让 MySQL 工作的所有内容都会产生类似的错误，如下所示：
