我需要一些帮助与后缀的configuration。 这是第一次。
我正在按照这个方法，仔细configuration每一步。 任何人都可以帮我解决这个错误吗？

您需要遵循当前的后缀configuration指南。
在所有这些警告Postfix，不理解或从您的configuration解释。 警报就在那里告诉你，预期的行为可能不会如预期的那样。 因此，请参阅man 5 postconf或查看http://www.postfix.org/postconf.5.html以获取正确的名称和参数。
smtpd_sasl_application_name（默认值：smtpd）Postfix SMTP服务器用于SASL服务器初始化的应用程序名称。 这将控制SASLconfiguration文件的名称。 缺省值是smtpd，对应于名为smtpd.conf的SASLconfiguration文件。
该function在Postfix 2.1和2.2中可用。 有了Postfix 2.3，它被重命名为smtpd_sasl_path。
摘录来自手册页。 所以基本上取而代之
smtpd_sasl_path=smtpd
这对我有效。
