今天之后我遇到了奇怪的问题。
几个月来我一直在使用 iRedMail 0.9.2，一点问题都没有。直到今天我都可以收发电子邮件。
今天我安装了apt-get install sendmail，但一切都停止了工作。
现在我无法接收和发送电子邮件。
因此我设法删除 sendmail 并重新安装 postfix，但是现在在 Roundcube 中当我尝试发送电子邮件时收到以下错误：
SMTP Error (451): Failed to add recipient "[email protected]" (4.3.0 <[email protected]>: Temporary lookup failure).
我删除了 sendmail 并重新安装了 postfix，如下所示：
sudo apt-get purge sendmail
sudo apt-get install --reinstall postfix
sudo /etc/init.d/postfix restart
以下是我的 mail.log 内容：

你能帮我解决这个问题吗？我认为我的 postfix 配置有误。

提前致谢！
答案1
warning: mysql:/etc/postfix/mysql/virtual_mailbox_domains.cf is unavailable. unsupported dictionary type: mysql
这很可能是由于缺少提供 mysql 查找支持的 postfix 扩展。在大多数发行版/包管理器中，该包被称为postfix-mysql，例如：
apt-get install postfix-mysql

迁移后您是否更新了域名的名称服务器？域名是否解析到新服务器？
