SMTP 邮件错误 452 4.3.1 系统存储空间不足

Question

我有一台使用 Postfix 作为邮件系统的服务器。我遇到的问题是我无法发送或接收电子邮件。如果我发送电子邮件，我会收到服务器的即时回复，其中显示：

Subject:    test
Sent:   16/05/2011 19:08

The following recipient(s) could not be reached:

'myemail@mydomain.com' on 16/05/2011 19:08
452 4.3.1 Insufficient system storage

我已检查以下内容：

磁盘空间，所有分区上都有千兆字节的可用空间。邮箱配额，任何邮箱都没有设置配额。

我清除了所有邮件日志并重新启动了服务器，但我仍然无法发送电子邮件。有没有人有任何指示供我下一步看。

我查看了该main.cf文件，结果如下：

Answer 1

从论坛帖子中我发现...

您是否设置了message_size_limit或queue_minfree？

您可能不需要设置queue_minfree，如果您没有至少1.5X的message_size_limit可用值（它可能错误地设置了一个很大的值），您将收到您指示的错误
