我试图找出这个configuration有什么问题。 我在/var/spool/postfix/maildrop （大约30k！）里面有很多邮件，而且这些邮件不会离开。 在日志中没有错误。
如果我试图在maildrop中重新发送一个消息， postsuper -r XXXXXXXXX失败。
我注意到，如果我使用sendmail（通过SSH连接）直接从服务器发送电子邮件，邮件进入队列，而不是如果我通过客户端发送邮件（例如雷鸟）邮件立即交付（使用相同的smtp服务器显然; spf和dkim得到正确应用）
maildrop中的所有“死邮件”都不会出现在qshape中：
qshape active deferred T 5 10 20 40 80 160 320 640 1280 1280+ TOTAL 11 0 0 0 0 0 0 0 0 0 11 example1.it 9 0 0 0 0 0 0 0 0 0 9 example2.com 1 0 0 0 0 0 0 0 0 0 1 example3.com 1 0 0 0 0 0 0 0 0 0 1
如果我发出通用postsuper -r ALL我得到less于100消息重新postsuper -r ALL 。
任何build议？ 我的configuration：

这个问题是由opendkim库引起的，即使在文档中声明它应该依赖于/etc/resolv.conf （并且只要我记得它就是这样），在我的情况下它被忽略了：
名称服务器（string）
提供以逗号分隔的IP地址列表，这些IP地址列表将在执行DNS查询以检索DKIM密钥，VBRlogging等时使用。这些列表将覆盖正在使用的parsing器的任何本地缺省值，这些缺省值可以在/ etc / resolv中定义.conf或硬编码到软件中 。
解决了将Nameservers参数添加到/etc/opendkim.conf 。
我会进一步调查，以了解是一个错误 ，还是一个错误的configuration。
