我是一种新的后缀，所以希望有人能指出我明显在这里我有一个Postfix的工作作为SMTP服务器，一切都很好的几天。 然后没有警告或明显的理由，我不能再发送邮件。
检查mail.log文件见：
warning: xxx-xxx-xxx-xxx.isp.domain.my[xxx.xxx.xxx.xxx]: SASL login authentication failed: authentication failure NOQUEUE: reject: RCPT from xxx-xxx-xxx-xxx.isp.domain.my[xxx.xxx.xxx.xxx]: 454 4.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<MyComputerName> 我尝试重新启动后缀，但它没有工作。 所以我重新启动电脑，工作。 仔细阅读我的想法是，SASL身份validation守护进程可能是个问题 – 但是每隔几天仍然需要启动该服务似乎并不富有成效。
有没有人有一个想法，我应该开始寻找问题/永久解决scheme？
编辑！ 根据要求，这是我的main.cf文件的内容。 注意EHCP放置了一些东西，我的控制面板解决scheme，postfix忽略了一个未使用的参数警告：

至于什么SASL解决scheme，我甚至不知道如何检查，对不起。
编辑2：重新启动saslauthd服务，而不是一个完整的重新启动也可以 – 我还没有想出是什么使服务停止工作，而仍然加载（PS显示在内存中）
想法？
