运行Debian 6，我相信我已经正确地启用了一切，遵循各种指南来仔细检查，因为我已经为此工作了3天。 我已经用telnettesting了dovecot和postfix，并且他们的工作情况最好，但是我在使用smtp时没有得到预期的SASL支持响应。 我真的不知道如何解决这个问题。
另外fwiw我注意到dovecot -n输出模式设置为432，因为它实际上在dovecot.conf中设置为0660，任何想法，为什么这可能是相关的？

你不应该只在公共服务器上运行SASL。
为传入邮件启用TLS和SASL，或者 – 更好地 – 在master.cf中configuration注释掉的提交监听器，并告诉人们使用它。
