我们最近在向我们的阵列添加新服务器时遇到了这个问题，我们通过确保我们拥有正确的 反向 DNS 查找 设置.
I'm using MDaemon as out mail server and the last days I get an error "554 Message does not conform to standards" for emails sent from one of the machines. Any idea what may be causing it? Other machines work fine.

SMTP error 554 is one of the more vague error codes, but is typically caused by the receiving server seeing something in the From or To headers that it doesn't like. This can be caused by a spam trap identifying your machine as a relay, or as a machine not trusted to send mail from your domain.
We ran into this problem recently when adding a new server to our array, and we fixed it by making sure that we had the correct reverse DNS lookup set up.
